MOOJAY · EB ADVENTURE SERIES
Full-suspension comfort, foldable utility, and long-range energy for city streets and outdoor routes.
WHY RIDERS CHOOSE EB50
A 250W rated motor, 48V 14.5Ah removable battery, hydraulic disc brakes, full suspension, and a three-step folding frame support commuting, storage, and weekend exploration.
01 / ALL-TERRAIN PERFORMANCE
The 250W rated brushless motor supports smooth acceleration and steady assistance across everyday roads and suitable outdoor routes. A 7-speed drivetrain helps match your pedaling cadence to changing terrain.
02 / FULL SUSPENSION
A hydraulic front suspension fork and rear air shock absorber work together to reduce ordinary bumps and vibration. The result is a more composed ride across pavement, cobbles, and suitable firm trails.
03 / BATTERY & RANGE
The 48V 14.5Ah battery can be charged on the bike or removed for indoor charging. Range is rated up to 55 km in electric-only mode and up to 80 km with pedal assistance under suitable conditions.
04 / FOLDING UTILITY
The frame, handlebar, and folding components reduce the EB50 to a more compact footprint without specialized tools. Folded dimensions of 105 × 67.5 × 79 cm help with home storage and suitable vehicle transport.
05 / BRAKING & CONTROL
Front and rear hydraulic disc brakes provide direct, progressive control with less hand effort than many cable-operated systems. Braking performance still depends on speed, load, surface, weather, tire grip, adjustment, and maintenance.

PURCHASE QUESTIONS, ANSWERED
The maximum motor-powered speed is 25 km/h (15.5 mph). Estimated range is up to 55 km (34.2 miles) in electric-only mode and up to 80 km (49.7 miles) with pedal assistance. Actual results vary with load, terrain, temperature, tire pressure, riding style, stops, and battery condition.
A full charge takes approximately 8 hours with the included 54.6V 2A charger. The 48V 14.5Ah battery can be removed for indoor charging or charged while installed on the bike.
The three-step folding frame reduces the bike to 105 × 67.5 × 79 cm (41.34 × 26.57 × 31.10 in). At 33 kg (72.75 lb), confirm that you can lift it safely or arrange assistance before loading it into a vehicle.
The maximum rider weight is 150 kg (330.7 lb). The rear rack is separately rated for up to 25 kg (55.1 lb). Secure cargo carefully and do not use the rack rating as an increase to the stated rider limit.
The adjustable saddle is intended for riders approximately 155 cm (5 ft 1 in) and taller, subject to individual fit. The fat tires and suspension suit paved streets and firm recreational routes where riding is permitted; reduce speed on loose, wet, icy, or uneven ground.
The listed modes are electric-only, regular pedal, pedal assist, cruise control, and walk assist. Mode availability and public-road use requirements vary by country and market configuration. Confirm local rules before using electric-only or cruise functions.
The EB50 uses a 250W rated brushless motor. The specification lists a maximum motor-powered speed of 25 km/h, maximum torque of ≤80 N·m, and motor speed of 470 rpm ±10. Market classification depends on the complete vehicle configuration and local rules.
The stated maximum climbing angle is up to 30° under suitable conditions. Actual climbing ability varies significantly with rider and cargo weight, battery charge, approach speed, surface grip, tire pressure, weather, and route length.
It uses front and rear hydraulic disc brakes for progressive braking control. Braking distance varies with speed, load, weather, surface, pad and rotor condition, tire grip, hydraulic-system condition, and maintenance.
A hydraulic front fork and rear air shock absorber help reduce ordinary impacts and vibration. Suspension improves comfort but does not remove the need to slow down for potholes, curbs, rough ground, or other hazards.
Unfolded size is 169.6 × 73 × 124.2 cm (66.77 × 28.74 × 48.90 in). Overall weight is 33 kg (72.75 lb), including an approximately 4 kg (8.82 lb) battery.
The EB50 arrives approximately 85% pre-assembled. Follow the included manual and assembly video, then check all fasteners, folding locks, wheels, brakes, handlebar alignment, tire pressure, battery lock, lights, and controls before riding.
The EB50 includes a 10W LED headlight, taillight, turn signals, and an LCD display. These features support visibility and information access but do not replace reflective clothing, situational awareness, or equipment required by local law.
Compatible batteries may be available separately. Contact xgyssp1@moojay.com with your EB50 model and order details before purchasing so voltage, capacity, connector, mount, and charger compatibility can be confirmed.
Brief exposure to light rain may occur during normal use, but prolonged rain, heavy downpours, standing water, flooding, submersion, and pressure washing should be avoided. Dry the bike fully before charging or storage.
Regularly check tire condition and pressure, brake response, pads and rotors, hydraulic lines, wheel security, drivetrain lubrication, folding locks, suspension, fasteners, lights, battery contacts, and charger condition. Have damaged or uncertain components inspected before riding.
Use the pressure range shown on the tire sidewall or in the supplied manual. Check pressure before rides, inspect for cuts or embedded objects, and replace damaged or excessively worn tires before use.
Use only the supplied charger or a replacement specifically confirmed as compatible by MOOJAY. An incorrect voltage, connector, polarity, or charging profile can damage the battery and create a safety risk.
EB50 emphasizes folding portability, hydraulic disc brakes, a larger 696Wh battery, and hydraulic-front/rear-air full suspension. EB51 emphasizes front and rear cargo carrying, mechanical disc brakes, and a lighter 30.2 kg overall weight. Compare fit, carrying needs, and storage requirements before choosing.
The bike has a two-year limited product warranty and the battery has a one-year limited warranty. Normal wear items such as tires and brake pads are excluded. Misuse, unauthorized modification, improper assembly, water ingress, accidents, and non-manufacturing damage are not covered.
