About this item

Product details

The KELOMA R20 Electric Mountain Bike is designed for adults and teens ages 16 and older seeking a comfortable and powerful ride across varied terrains. It features front and rear hydraulic disc brakes for responsive stopping control and smooth, progressive adjustment of braking force. Equipped with a 750W brushless rear hub motor delivering up to 90 N·m of torque, this Class 3 pedal assist electric bike supports speeds of up to 28 MPH with five assistance levels. Its removable 48V 20Ah lithium-ion battery provides 960Wh of capacity and an estimated range of 30–40 miles using throttle power or 40–90 miles with pedal assist. The battery can be charged on or off the bike, with a full charge taking approximately 7–8 hours. Actual speed and range vary with rider weight, terrain, assistance level, temperature, and riding style. The full suspension system, featuring a front fork and rear spring shock, works with the wide 20 x 4.0-inch fat tires to help absorb bumps and provide stability on dirt, gravel, grass, and sand. A Shimano 7-speed drivetrain offers versatile gearing for changing terrain. Riders can monitor speed, battery level, mileage, and pedal-assist status on the color LCD and connect to an app for electronic locking and ride-data review. Two included NFC card keys allow riders to tap the display to turn the bike on or off. An LED headlight, rear brake light, and turn signals enhance visibility, while front and rear fenders help reduce mud and water spray. The extended 23.6-inch cushioned seat and high-carbon-steel frame provide a comfortable riding platform with a maximum load capacity of 450 lb. The R20 is recommended for riders approximately 4 ft 11 in to 6 ft 3 in tall. Its electrical system is certified to UL 2849, and the bike arrives approximately 80% pre-assembled for easier setup.

Warranty

Warranty information

KELOMA ONE-YEAR LIMITED WARRANTY WARRANTY PERIOD KELOMA warrants the original retail purchaser that a new KELOMA electric bicycle will be free from defects in materials and workmanship under normal and intended use for one year from the original date of purchase. This warranty applies only to products purchased new from KELOMA or an authorized retailer and is not transferable. WHAT IS COVERED During the warranty period, this limited warranty covers verified manufacturing defects affecting the normal operation of the electric bicycle, including defects in the frame, motor, battery, controller, display, charger, wiring system, suspension components, brakes, drivetrain components, lights, and other original non-consumable parts supplied with the product. Coverage applies only when the electric bicycle has been properly assembled, operated, charged, stored, and maintained according to the user manual. Components must have been used within the stated rider weight, cargo capacity, speed classification, terrain, temperature, and operating limitations. BATTERY COVERAGE The original battery is covered against verified defects in materials, workmanship, and electrical operation during the warranty period. Normal reduction in battery capacity caused by age, charging cycles, use, temperature, or storage is not considered a manufacturing defect. Battery damage caused by improper charging, use of an incompatible charger, deep discharge, extended storage without maintenance charging, exposure to extreme temperatures, water intrusion, impact, puncture, unauthorized opening, or modification is not covered. Only the original KELOMA-approved charger should be used. ITEMS NOT COVERED This limited warranty does not cover: 1. Normal wear and routine maintenance, including tires, inner tubes, brake pads, brake rotors, chains, freewheels, cables, grips, pedals, saddles, bearings, paint, decals, and similar wear items, unless defective when received. 2. Cosmetic damage that does not affect normal operation, including scratches, fading, discoloration, dents, surface corrosion, or normal finish wear. 3. Damage caused by accident, collision, abuse, neglect, improper storage, overloading, improper transportation, misuse, competitive riding, stunts, jumping, or use outside the stated intended riding conditions. 4. Damage caused by incorrect assembly, improper adjustment, insufficient maintenance, installation errors, or failure to follow the user manual. 5. Damage caused by water immersion, flooding, pressure washing, severe weather exposure, fire, excessive heat, freezing conditions, chemicals, or environmental corrosion. 6. Damage caused by incompatible accessories, replacement parts, batteries, chargers, controllers, or electrical components. 7. Damage directly caused by unauthorized modification, improper repair, alteration of wiring, removal of safety equipment, or changes to the motor power, controller, speed limiter, firmware, or e-bike classification. 8. Products used for commercial delivery, rental, fleet service, competition, or other commercial purposes unless separately approved in writing by KELOMA. 9. Products with a removed, altered, damaged, or unreadable serial number or identification label. 10. Damage occurring after delivery that is unrelated to a manufacturing defect. WARRANTY REMEDY For an approved warranty claim, KELOMA will, at its option, repair the defective component, provide a replacement component of equivalent function, or replace the product when repair or part replacement is not reasonably available. A refund may be provided when required by applicable law. Replacement parts may differ slightly in color or appearance but will provide substantially equivalent function. Warranty service does not extend the original warranty period unless required by applicable law. The warranty covers approved replacement parts. Third-party inspection, assembly, installation, repair, transportation, and labor charges are not covered unless authorized in writing by KELOMA before the service is performed. Do not return the complete bicycle, battery, or other component without receiving return instructions and authorization. HOW TO OBTAIN WARRANTY SERVICE To request warranty service, contact KELOMA and provide: 1. The purchaser's name and contact information. 2. A copy of the original sales receipt or order confirmation. 3. The bicycle model and serial number. 4. A clear description of the problem. 5. Clear photographs or video showing the reported defect. 6. Any additional troubleshooting information reasonably requested. Stop using the bicycle if continued operation could cause injury or additional damage. KELOMA may request basic troubleshooting or inspection before approving replacement parts or other warranty service. Contact Information: Email: [support@keloma-ebike.com](mailto:support@keloma-ebike.com) Website: [www.keloma.shop](http://www.keloma.shop) LIMITATION OF LIABILITY To the extent permitted by applicable law, KELOMA is not responsible for indirect, incidental, special, or consequential damages arising from the use or inability to use the product. Some states do not allow limitations on incidental or consequential damages, so this limitation may not apply to you. Any implied warranties, including warranties of merchantability or fitness for a particular purpose, are limited to the duration of this written warranty to the extent permitted by applicable law. Some states do not allow limitations on the duration of implied warranties, so this limitation may not apply to you. STATE LAW RIGHTS This limited warranty gives the purchaser specific legal rights. The purchaser may also have other rights that vary by state. Nothing in this warranty limits any rights or remedies that cannot be excluded or limited under applicable law. This warranty is separate from the retailer's return and refund policy. Returns must follow the terms and deadlines of the retailer from which the product was purchased.
