Finding a reliable mini bike that won’t leave you stranded or require constant tinkering is harder than most buyers expect. Many models look great in photos but arrive with loose hardware, undersized components, or engines that struggle to start after a few weeks of use.

I’m Amir — the founder and writer behind Four Wheel Ask. I specialize in analyzing small-engine vehicle specifications, comparing frame and component build quality across manufacturers, and aggregating long-term owner feedback to separate genuine value from marketing hype.

After analyzing hundreds of owner reviews, I’ve identified the most dependable best mini bike models for both children and adults.

How To Choose The Best Mini Bike

Choosing the right mini bike means looking past the photos and focusing on what actually determines whether a machine will run reliably for years or spend most of its time waiting for replacement parts. The most important factors are engine type and displacement, rider fit, braking and suspension quality, and the level of assembly and ongoing maintenance required.

Engine Type and Displacement

A four-stroke engine is almost always the better choice for reliability and ease of use. Four-strokes run on regular gasoline without premixing oil, produce less noise, and typically last longer than two-stroke equivalents. Displacement — measured in cubic centimeters (cc) — directly affects power output and top speed. For young children, 40cc to 50cc engines provide safe, manageable acceleration. For teens and adults, 99cc to 105cc models deliver enough torque for trail riding, while 196cc engines approach full-size dirt bike performance. Electric models offer instant torque and quieter operation but require careful attention to battery capacity and recharge time.

Rider Size and Weight Capacity

A mini bike that is too large or too small for the rider is unsafe and unpleasant to ride. Manufacturers list minimum seat heights and maximum weight limits, but real-world feedback often reveals that these numbers are optimistic. A bike rated for 185 pounds may struggle at 170 pounds on a steep grade. Seat height is critical for younger riders, who need to plant both feet flat at stops. For adults, look for models with at least 38 inches of overall length and adjustable handlebars to avoid a cramped riding position.

Brakes, Suspension, and Safety Features

Reliable stopping power is non-negotiable, especially for young riders. Disc brakes — either mechanical or hydraulic — provide consistent performance in wet or muddy conditions. Drum brakes are less effective and more prone to fade. Front and rear suspension improves control on uneven terrain and reduces fatigue on longer rides. For children, features like adjustable throttle limiters and parental speed controls add an extra layer of safety while they develop riding skills. Always check that the bike meets EPA or CARB approval if emissions regulations apply in your area.

In‑Depth Reviews

Best Overall

1. Coleman Powersports B100 105cc Minibike

105cc 4-Stroke OHVRear Disc Brake

The Coleman B100 stands out for its trusted brand reputation and sensible engineering. The 105cc overhead-valve four-stroke engine provides sufficient torque for trail riding while keeping noise and fuel consumption lower than cheaper two-stroke alternatives. Owner reports consistently highlight straightforward assembly — most users have the bike running within 30 minutes of unboxing — and the low-pressure tires offer real traction on loose dirt and grass without excessive vibration at moderate speeds.

Several long-term owner reviews note that the B100 feels properly sized for both older children and smaller adults. The 150-pound weight limit is conservative compared to some competitors, but actual riding feedback suggests the frame and suspension handle that load comfortably on flat to moderately uneven terrain. The rear disc brake delivers reliable stopping power, though a few owners mention that upgrading the brake line improves feel and durability over time. Top speed stock sits around 22 mph, which is fast enough to be exciting without being overwhelming for newer riders.

Build quality is a clear step above entry-level mini bikes. The heavy-duty frame shows consistent welds, the pull-start mechanism rarely hangs up, and the air-cooling system keeps engine temperatures in check during extended sessions. The most common complaints involve minor assembly alignment issues and an occasional gasket leak that Amazon customer service typically resolves with a partial refund or replacement part. For riders who want a ready-to-ride machine from a brand with decent parts availability, the B100 is the most balanced option on the market.

What works

  • Trusted brand with better parts availability than generic imports
  • Quick assembly — most owners riding within 30 minutes
  • Smooth, predictable power delivery suitable for beginners

What doesn’t

  • Stock suspension and brake lines benefit from upgrades
  • Some units arrive with minor gasket or alignment issues
Performance

2. Windone RM7 Electric Dirt Bike

2200W Peak MotorDual Hydraulic Brakes

The Windone RM7 delivers genuine electric dirt bike performance at a price that undercuts most comparable gas models. The mid-drive 2200-watt peak motor provides instant torque and the three speed modes — capped at 15, 22, and 37 mph — let riders gradually build confidence before unlocking full power. Owner feedback consistently praises the geared hub motor’s smooth power curve and the lack of power sag even during extended hill climbs, which suggests the battery management system is well-tuned.

Battery range is a strong point for this category. The 48-volt 22.5 amp-hour pack delivers between 37 and 45 miles per charge under normal riding conditions, and the 6 to 7 hour recharge time is reasonable for overnight charging. The dual hydraulic disc brakes provide significantly better stopping power than the mechanical disc brakes found on most sub-1,000 dollar electric bikes. Owners report that the brakes need an initial bleed to feel perfect, but once set, they remain consistent even in wet conditions.

Build quality is impressive for the price point. The frame feels solid at 130 pounds, the 14-inch front and 12-inch rear fat tires absorb trail chatter effectively, and the front fork and rear nitrogen shock offer genuine suspension travel rather than just cosmetic spring assemblies. Assembly requires some mechanical patience — the brake setup instructions are vague — but most owners report completing the build in under one hour. The IPX6 waterproof rating adds peace of mind for riders who encounter puddles or muddy trails.

What works

  • Explosive yet controllable acceleration from geared hub motor
  • Useful 37 to 45 mile real-world range
  • Dual hydraulic brakes outperform mechanical discs

What doesn’t

  • Brake instructions unclear during assembly
  • Heavier than expected at 130 pounds
Premium

3. EGO Power+ MB1000 Electric Mini Bike

Battery Not IncludedDual Hydraulic Disc

The EGO Power+ MB1000 is the quietest and most refined mini bike on this list, but it comes with a major caveat: batteries and charger are sold separately. For owners who already own EGO yard tools, this is a seamless investment. For new buyers, the upfront cost spikes significantly once you factor in two 7.5 amp-hour batteries. Owner reviews confirm that with two 7.5Ah batteries, a 200-pound rider gets roughly 45 minutes of continuous riding, and swapping in larger 12.5Ah batteries extends that substantially.

Build quality is exceptional across every component. The alloy steel frame features a smooth powder coat finish, the hydraulic disc brakes offer progressive stopping power, and the front and rear suspension delivers genuine damping that makes rough terrain feel manageable. The digital display tracks speed, acceleration, and remaining range, though several owners note the screen is difficult to read in direct sunlight. The onboard storage compartment fits an extra battery for extended rides, and the IPX4 weather rating allows riding in light rain without concern.

Performance-wise, the hub motor pushes the bike to a genuine 28 mph on flat ground. The three driving modes — ECO, Normal, and Sport — combined with a parental speed limiter hidden under the seat make this bike adaptable for different skill levels. The LED headlight is bright enough for dusk riding, and the included mirror mounts are a thoughtful touch for riders who want to add mirrors for neighborhood cruising. The most common criticism involves a finicky READY switch that occasionally requires multiple presses to engage, which EGO could address with a firmware update.

What works

  • Superb build quality and paint finish
  • Quiet operation with genuine 28 mph top speed
  • Interchangeable batteries with EGO yard tool ecosystem

What doesn’t

  • Batteries and charger not included — significant added cost
  • Display hard to read in bright sunlight

4. M Massimo Motor Warrior200 196CC

196cc 6.5 HP19 Inch AT Tires

The Massimo Motor Warrior200 is a full-size mini bike that bridges the gap between youth-oriented models and full-size dirt bikes. The 196cc four-stroke engine produces a genuine 6.5 horsepower, giving it enough grunt to carry adult riders up to moderate inclines without bogging down. The automatic transmission with dry clutch and chain drive keeps operation simple — twist and go — which is rare in this displacement class. Owners consistently report that the bike feels substantial and well-proportioned for larger riders.

The 19-inch AT tires are a defining feature of this model. They provide the ground clearance and traction needed for serious off-road use, and the rugged tread pattern sheds mud effectively. The bike ships fully assembled, which eliminates the most common source of frustration with budget mini bikes. However, several owner reports note that while the frame and engine are solid, some ancillary components — foot pegs, kickstand, and throttle assembly — use cheaper materials that may need replacement within the first season of regular use.

Parts availability is the biggest concern with the Warrior200. Multiple owners report difficulty sourcing replacement parts when something breaks, and customer service response times have been inconsistent. The engine itself is robust and starts reliably when properly maintained, but the surrounding components require more attention than the price point might suggest. For riders who are comfortable sourcing generic replacement parts and performing their own maintenance, this bike offers impressive engine performance for the money.

What works

  • Powerful 196cc engine with real 6.5 HP output
  • Large 19-inch AT tires for serious off-road capability
  • Ships fully assembled — no build time

What doesn’t

  • Cheaper peripheral components may need early replacement
  • Parts availability and customer service are inconsistent

5. Oryxearth BRM100 Mini Dirt Bike

105cc 4-Stroke28 Mph Top Speed

The Oryxearth BRM100 delivers a compelling combination of displacement and price that appeals to budget-conscious buyers who want a 105cc engine without paying premium-brand prices. The four-stroke engine is EPA-compliant and runs on regular unleaded gasoline, keeping operating costs low. Owner reports indicate that the pull-start mechanism is reliable when the engine is warm, though cold starts sometimes require multiple pulls and careful throttle feathering to keep the engine running.

Rider fit is a strong point for this model. The recommended height range of 4 foot 3 to 5 foot 9 covers a wide spectrum, and the 185-pound weight limit is realistic for teenage and smaller adult riders. The low-pressure pneumatic tires provide decent grip on hard-packed dirt and grass, and the rear disc brake offers adequate stopping power once properly adjusted. Several owners note that the front fender tends to vibrate at higher speeds initially but settles after a break-in period of about two months.

Maintenance requirements are moderate but specific. The oil fill location is awkward and requires a funnel and the front wheel to be elevated for easy access. Some owners report that the gas tank cap can leak intermittently, and the engine may die when coasting from full throttle — an issue that often improves as the carburetor tuning stabilizes with use. The 60-day parts warranty and 90-day engine warranty provide a safety net, though owners who ride primarily in mud or wet conditions report accelerated brake and clutch wear.

What works

  • Broad height range suits teens and smaller adults
  • Fuel-efficient 105cc engine with EPA approval
  • Good grip from low-pressure off-road tires

What doesn’t

  • Cold starts require patience and technique
  • Gas cap and throttle response quirks need attention
Battery

6. XtremepowerUS 99cc Mini Bike

99cc 3.5 HPRear Disc Brake

The XtremepowerUS 99cc mini bike is designed around a simple formula: a proven 4-stroke OHV engine mounted in a sturdy metal frame with low-pressure tires for soft terrain. The 3.5 horsepower output is modest by adult standards but perfectly adequate for teenagers and smaller adults exploring dirt paths and grassy fields. Owner feedback highlights the bike’s ability to carry loads of up to 200 pounds without significant performance loss, which exceeds the official rating and suggests the frame and clutch are built with some margin.

Assembly is generally straightforward, though the handlebar installation requires some wrestling to align properly. The bright rechargeable LED headlight is a nice inclusion for dusk riding, though its mounting bracket can be fragile. Several owners report that the throttle cable may fail prematurely — some within the first few rides — but XtremepowerUS customer service has a track record of sending replacements quickly. The rear disc brake provides sufficient stopping power for the bike’s top speed, but the brake pads wear faster than expected under regular use.

The most significant reliability concern involves the kickstand, which has been reported to crack after repeated use on soft ground. Owners who reinforce the kickstand mount or park on hard surfaces avoid this issue entirely. The engine itself starts reliably with the pull-start mechanism when cold, and the 4-stroke design eliminates the hassle of mixing oil and gasoline. For families who want a weekend trail bike that doesn’t require premium maintenance, this model delivers solid value as long as you address the known weak points proactively.

What works

  • Handles loads up to 200 pounds without struggling
  • Rechargeable LED headlight for low-light visibility
  • Simple 4-stroke engine with no oil mixing needed

What doesn’t

  • Throttle cable and kickstand are known weak points
  • Brake pads wear faster than expected

7. GugoIs G16 Electric Bike

750W Peak MotorDual Suspension

The GugoIs G16 positions itself as a versatile electric commuter with moped-style comfort, and it delivers on that promise for riders who prioritize utility over outright performance. The 750-watt peak motor achieves 28 mph on flat ground, and the 48-volt 15.6 amp-hour battery provides a real-world range of around 30 miles in pedal-assist mode. The dual suspension system smooths out pavement cracks and light gravel, though heavier riders near the 185-pound mark report that the suspension bottoms out on larger bumps.

Feature density is where the G16 punches above its price class. The included rear child seat, front basket, remote alarm, and USB charging port make this bike genuinely practical for parents running errands with a young child. The folding frame reduces storage footprint, though at 68 pounds it is still heavy enough to make carrying up stairs a challenge. The disc brakes offer adequate stopping power, and the bright headlight and taillight improve visibility during evening rides.

Build quality is mixed. The high-carbon steel frame feels sturdy, but some owners have reported minor cosmetic issues like broken mounting tabs on included accessories. Assembly takes about three hours for a first-time builder, and the instruction manual could be clearer. The battery is UL2849 certified, which adds a layer of safety confidence. For riders who want an electric mini bike that can double as a grocery-getter and school-run vehicle, the G16 offers exceptional versatility at a budget-friendly price.

What works

  • Includes rear child seat, basket, alarm, and USB port
  • Dual suspension provides a comfortable ride
  • UL certified battery for safety peace of mind

What doesn’t

  • Suspension bottoms out for heavier riders
  • Assembly takes several hours with unclear instructions
Design

8. Caroma Z20 Electric Scooter with Seat

1000W Peak Motor20 Inch Off-Road Tires

The Caroma Z20 blends retro motorcycle styling with modern electric scooter practicality. The 500-watt continuous motor peaks at 1000 watts, delivering enough torque to reach 20 mph and climb moderate hills at 11 to 15 mph. The 48-volt 374 watt-hour battery is UL 2272 certified and provides between 11 and 12 miles of real-world range under throttle-only use, which is roughly half the advertised 25-mile figure. Riders who pedal-assist or stay on flat ground can extend that range closer to 18 miles.

Comfort is the Z20’s strongest attribute. The wide, thick seat is genuinely comfortable for extended rides, and the 20 by 3 inch off-road tires combined with front and rear suspension absorb bumps effectively. The large front basket is practical for carrying groceries, backpacks, or small pets. The dual disc brakes provide confident stopping power, and the LCD display shows real-time speed, battery level, and remaining range. The three adjustable speed modes allow newer riders to start slow and build confidence.

The main limitations relate to battery life and ergonomics. Owners consistently report that the claimed 25-mile range is optimistic by about 50 percent under real-world conditions. The handlebar height and peg position are not adjustable, which can make the riding position feel cramped for taller riders above 5 foot 10. The vintage styling is polarizing — some love the retro look while others find it bulky. Assembly is straightforward, and the included toolkit contains everything needed for the build.

What works

  • Extremely comfortable thick seat for long rides
  • Retro styling with practical front basket
  • Dual suspension and disc brakes provide a smooth ride

What doesn’t

  • Real-world range is about half the advertised figure
  • No adjustable handlebars or pegs for taller riders

9. AYOLNY EB1L Foldable Electric Bike

1000W Peak MotorFolding Frame

The AYOLNY EB1L is a lightweight, foldable electric bike designed for commuters who need to blend cycling with public transit or car storage. The 1000-watt peak motor provides enough power for 15-degree hill climbs, and the three riding modes — electric only, pedal assist, and manual — offer flexibility for different energy levels and terrain. The 36-volt 7.8 amp-hour battery delivers 15 miles in throttle-only mode and up to 25 miles with pedal assist, which matches real-world owner reports.

Portability is the headline feature. At 48.9 pounds with a folding frame, this bike fits into car trunks, subway cars, and office storage closets. The 14-inch wheels keep the folded package compact but do compromise stability at higher speeds compared to larger-wheeled bikes. The drum brakes provide reliable stopping power in dry and wet conditions, and the integrated LED lights improve visibility. Owner reviews consistently praise the ease of assembly — the bike arrives 90 percent assembled with clear instructions.

The main trade-off for the folding design is ride quality. The smaller wheels transmit more road vibration than 20-inch or 26-inch wheels, and the ride can feel twitchy at speeds above 18 mph. Several taller riders report that the pedals sit too close to the ground, causing them to scrape during tight turns. The battery range is adequate for short commutes but may fall short for riders expecting to travel more than 10 miles each way without recharging. For urban commuters who prioritize portability over comfort, this is a solid entry-level choice.

What works

  • Lightweight folding design fits in car trunks and subways
  • Three riding modes offer flexibility for different needs
  • Quick assembly with clear instructions

What doesn’t

  • Small wheels transmit road vibration and feel twitchy at speed
  • Pedal clearance too low for taller riders

10. FRP MB40 40CC Mini Bike

40cc 4-Stroke165 Lbs Capacity

The FRP MB40 is a purpose-built starter bike for young children, and it succeeds in that role by keeping power output low and the seat height manageable. The 40cc four-stroke engine is quiet and does not require oil mixing, which simplifies refueling for parents. The automatic transmission means no clutch or gear shifting — twist the grip and go. Owner reports indicate that children as young as six years old can ride comfortably, and the bike fits well up to about age ten, depending on the child’s height.

Safety features are appropriately scaled for this age group. The dual disc brakes provide better stopping power than drum brakes found on many competitor models at this price point. The engine has a governed top speed around 18 mph, which is fast enough to be fun but slow enough to keep the risk manageable on flat terrain. The alloy steel frame feels durable, and the unified bolt system for fenders and seat covers reduces the chance of loose fasteners during rides. The pull-start mechanism is easy for adults to operate and rarely sticks.

The most common criticism involves the brake lever reach. Younger children with smaller hands struggle to squeeze the levers effectively, which can be a safety concern. There is no foot brake or remote shutoff as a backup. Assembly is straightforward with all tools included, and the 60-day parts replacement policy with prepaid return label is better than average for this price tier. Some owners report that the engine became harder to start after several months of use, often requiring carburetor cleaning or throttle cable adjustment.

What works

  • Quiet 4-stroke engine with no oil mixing required
  • Dual disc brakes provide good stopping power for the size
  • Easy assembly with included tools and unified bolt system

What doesn’t

  • Brake levers are hard for small children to reach
  • No foot brake or remote shutoff for emergency stops
Budget

11. X-PRO 40cc Kids Dirt Bike

40cc 4-Stroke80 Lb Capacity

The X-PRO 40cc is the entry point for families who want a gas-powered mini bike at the lowest possible cost. The 40cc four-stroke engine is EPA-approved and produces gentle acceleration that suits children ages four to nine. The 80-pound weight limit is the lowest on this list, which is appropriate for the intended age range but means most children will outgrow the bike within one to two seasons. The low seat height of 23 inches allows even very young riders to plant both feet on the ground.

Long-term owner reports are mixed but trend positive for families who understand the bike’s limitations. Several owners report that the bike still runs well after two years of regular use, with only minor issues like chains that require periodic tightening. The 4-stroke engine has proven more reliable than 2-stroke alternatives at this price point, and the disc brake offers adequate stopping power for low-speed riding. The twist-grip throttle is intuitive for young children who have never ridden before.

The most serious reliability concern involves the chain, which multiple owners report popping off repeatedly. Some have received replacement chains that were the wrong size, and customer service response times have been inconsistent. The bike requires assembly of the handlebar brackets, wheels, brakes, number plate, and fender, which takes about an hour for a mechanically inclined adult. For budget-conscious families with small children who want a starter bike for paved paths and flat grass, the X-PRO represents the lowest financial commitment, but the chain issue is a real drawback.

What works

  • Lowest seat height suits very young riders aged 4 to 9
  • EPA-approved 4-stroke engine is reliable when maintained
  • Gentle acceleration builds confidence in beginners

What doesn’t

  • Chain pops off frequently on some units
  • Children outgrow the 80-pound capacity quickly

Hardware and Specs Guide

Four-Stroke Engine Reliability

The majority of gas-powered mini bikes on the market now use four-stroke engines, which run on straight gasoline without premixing oil. Four-stroke engines produce less noise, emit fewer fumes, and typically require less frequent maintenance than two-stroke equivalents. The most common displacements are 40cc for young children, 99cc to 105cc for teens and smaller adults, and 196cc for larger riders seeking near-full-size performance. Look for overhead valve (OHV) designs, which offer better fuel efficiency and cooler operation than side-valve engines.

Electric Motor and Battery Considerations

Electric mini bikes and scooters use hub motors or mid-drive motors with power ratings from 500 watts to 2200 watts peak. Battery capacity is measured in watt-hours (Wh) or amp-hours (Ah) at a given voltage — a 48V 15.6Ah pack stores roughly 749 Wh. Real-world range is typically 50 to 70 percent of advertised figures depending on rider weight, terrain, and throttle usage. UL certification (UL 2272 or UL 2849) indicates that the battery and electrical system have passed safety testing for overcharge, over-discharge, and thermal runaway protection.

Braking Systems Compared

Disc brakes are the standard for mini bikes at all but the lowest price points. Mechanical disc brakes use a cable to actuate the caliper and are adequate for bikes under 25 mph. Hydraulic disc brakes use fluid pressure for more consistent stopping power with less hand effort and are preferred for electric bikes that reach higher speeds. Drum brakes are occasionally found on budget models but offer weaker stopping power and are more prone to fade during repeated use. Always check whether both front and rear brakes are disc type — some budget models only fit a disc on the rear.

Frame Geometry and Rider Fit

Mini bike frames vary significantly in overall length, seat height, and handlebar position. A bike that fits properly allows the rider to plant both feet flat at a stop while maintaining a slight bend in the knees. Minimum rider height is typically listed in inches or feet, but owner reports often reveal that these numbers are optimistic — add two to three inches to the recommended minimum for a comfortable fit. Weight capacity should account for the rider plus any gear, and exceeding the rated limit stresses the clutch, brakes, and suspension components.

FAQ

What age is a 40cc mini bike suitable for?
A 40cc mini bike is generally appropriate for children aged 4 to 9 years old, depending on the child’s height and coordination. The low seat height and gentle acceleration make these bikes ideal for first-time riders who are still developing throttle control and balance. Always supervise young riders and ensure they wear a DOT-certified helmet and appropriate protective gear.
How much assembly is typically required for a mini bike?
Most gas mini bikes arrive 70 to 90 percent assembled and require installation of the handlebars, front wheel, fenders, seat, and number plate. Assembly typically takes 30 minutes to 2 hours depending on mechanical experience and tool availability. Electric mini bikes and scooters often require less assembly, usually just handlebar attachment and battery installation. All necessary tools are typically included.
Do I need a license to ride a mini bike?
Licensing requirements vary by state and local jurisdiction. In many areas, mini bikes are classified as off-road vehicles and cannot be legally ridden on public streets, sidewalks, or bike paths. Some states require riders under a certain age to wear a helmet, and others may require registration or a safety certificate. Check your local Department of Motor Vehicles or equivalent agency before purchasing.
Should I choose a gas or electric mini bike?
The choice depends on your priorities. Gas mini bikes offer longer range, faster refueling, and higher top speeds in the same price bracket, but produce noise and exhaust fumes that may not be suitable for residential neighborhoods. Electric mini bikes are quieter, require less maintenance, and have lower operating costs, but battery range is limited and replacement batteries can be expensive. For young children riding close to home, electric is often the better choice. For teenagers and adults riding trails, gas provides more flexibility.
How fast does a 99cc or 105cc mini bike go?
A 99cc to 105cc four-stroke mini bike typically reaches top speeds between 22 and 28 mph stock, depending on rider weight, terrain, and gearing. Some models can be modified with upgraded exhaust and air filters to increase top speed by 5 to 10 mph, but this may void the warranty and should only be done by experienced mechanics. These speeds are fast enough for trail riding but manageable for teenagers with basic riding experience.
What maintenance does a four-stroke mini bike require?
Four-stroke mini bikes require regular oil changes every 10 to 20 hours of operation, chain lubrication and tension adjustment, air filter cleaning, and spark plug inspection. The pull-start mechanism should be checked periodically for wear. Fuel should be stabilized if the bike will sit for more than 30 days. Electric mini bikes require significantly less maintenance, mainly tire pressure checks, brake adjustments, and battery storage at partial charge during long periods of non-use.

Final Thoughts: The Verdict

For most buyers, the best mini bike winner is the Coleman Powersports B100 because it combines a reliable 105cc engine, straightforward assembly, and trusted brand support at a fair price point. If you want instant torque and zero maintenance on oil changes, grab the Windone RM7 for its impressive electric performance and genuine trail capability. And for families introducing very young children to riding, the FRP MB40 offers the most appropriate size and safety features at the lowest cost of entry.
