The Tamobyke V20 Pro electric bike is a moped-style fat-tire e-bike designed for riders seeking strong motor support, full suspension, and added rear utility capacity. Its rear hub motor is rated at 1,000W and can reach 1,500W peak output, with up to 90 Nm of torque for hills, acceleration, and mixed-surface riding.
A removable 48V 18.2Ah battery supports longer recreational rides, while the 20 × 4-inch fat tires, hydraulic disc brakes, and full-suspension system help provide control and comfort across pavement, gravel, and uneven routes.
The rear frame can support compatible cargo accessories when installed and loaded according to the manufacturer’s instructions. It should not be treated as an approved passenger seat unless the exact seat, foot supports, weight limit, installation method, and passenger use are specifically authorized for this model.
Range, speed, and performance figures come from manufacturer testing and are not guaranteed in everyday use. Actual results depend on rider and cargo weight, speed, pedal-assist level, throttle use, terrain, elevation, temperature, wind, tire pressure, battery condition, and maintenance.
The listed top speed may exceed e-bike limits in some US locations. Check state and local rules for public roads, bike lanes, parks, and trails, and use compliant settings where required.

Motor and Performance
The 1,000W rated rear hub motor can deliver up to 1,500W of peak output and 90 Nm of torque. This provides support for acceleration, hills, and riding with added cargo within the bike’s approved limits.
Tamobyke lists a maximum speed of up to 32 mph. Actual speed depends on rider weight, battery charge, terrain, wind, tire pressure, and the selected assistance or throttle setting.
Because the V20 Pro is heavier and faster than a conventional bicycle, riders should become familiar with its throttle response, braking distance, turning radius, and low-speed handling before using higher settings.
Battery and Range
The removable 48V 18.2Ah battery provides approximately 873.6Wh of listed capacity. It can be charged while installed on the bike or removed for charging in a suitable indoor location.
Tamobyke lists a maximum pedal-assist range of up to 80 miles under favorable test conditions. This figure should be used for comparison rather than as a guaranteed riding distance.
Higher speeds, frequent throttle use, hills, heavier loads, cold weather, strong wind, low tire pressure, and battery wear can reduce range.
Charging
The bike includes a 54.6V 2A charger, with a manufacturer-listed charging time of approximately 7 to 8 hours.
Charge the battery in a dry, ventilated area using the supplied or manufacturer-approved charger. Inspect the battery, charging port, cables, and charger before use, and discontinue charging if the equipment becomes damaged, swollen, unusually hot, or produces an unusual odor.
Full Suspension
The full-suspension system combines front and rear shock absorption to help reduce vibration and impacts from rough pavement, gravel, and uneven surfaces.
Suspension can improve comfort and wheel control, but it does not make the bike suitable for every jump, trail, or technical off-road route. Riding speed and tire pressure should be adjusted for the surface and conditions.
Fat Tires and Handling
The 20 × 4-inch fat tires provide a wide contact area for grip and stability on pavement and mixed surfaces.
The wide tires, long moped-style frame, and approximately 103 lb bike weight create a heavier riding feel than a standard bicycle. Allow extra room when turning, braking, parking, or moving the bike without motor assistance.
Hydraulic Brakes and Gearing
The V20 Pro uses hydraulic disc brakes for controlled stopping. Riders should inspect the brake pads, rotors, hoses, and lever feel regularly, particularly when riding at higher speeds or carrying cargo.
A Shimano 7-speed drivetrain provides mechanical gearing for climbing, cruising, and pedal-assisted riding. Selecting an appropriate gear can make pedaling more comfortable and reduce unnecessary strain on the drivetrain.
Rear Utility Frame
The included rear frame provides a mounting area for compatible utility accessories and secured cargo. Tamobyke’s current V20 Pro information describes an upgraded rear rack with a maximum cargo capacity of 50 lb.
Keep rear cargo centered, balanced, and securely attached. The weight of the rider, accessories, and cargo must remain within the bike’s total 330 lb payload capacity.
Do not carry a passenger unless Tamobyke specifically approves the exact seating system, foot supports, mounting hardware, passenger limits, and use for this model. A rear cargo frame or padded surface alone does not confirm passenger approval.
Display and Controls
The detachable digital LCD display provides access to speed, battery level, assistance settings, and ride information.
The bike also includes five pedal-assist levels and a twist throttle. Riders should learn how each control responds in a safe area before entering traffic or riding on busy paths.
Size and Weight
The bike weighs approximately 103 lb with the battery and has a listed maximum payload of 330 lb. Payload includes the rider, cargo, and any accessories attached to the bike.
Tamobyke recommends the V20 Pro for riders approximately 5’6″ to 6’4″ tall. Body proportions and riding preferences vary, so riders near either end of the range should check the listed measurements before ordering.
Its weight should also be considered when planning stair access, indoor storage, vehicle transport, maintenance, or use with a hitch-mounted bike rack.
Recommended Use
The Tamobyke V20 Pro may suit:
- Mixed-surface commuting
- Longer recreational rides
- Paved roads and gravel routes
- Riders who prefer a moped-style seating position
- Light cargo use with compatible rear accessories
- Riders comfortable handling a heavy fat-tire e-bike
- Routes where its motor output and speed settings are permitted
It may be less practical for frequent stair carrying, compact indoor storage, lightweight transport racks, or riders seeking the feel of a conventional bicycle.
