MOOJAY · ET MOBILITY SERIES
Compact freedom, stable control, and supportive comfort for independent everyday mobility.
WHY RIDERS CHOOSE ET50P
A compact three-wheel platform, supportive seating, straightforward controls, and a removable battery come together in one practical mobility solution.
01 / FOLDABLE MOBILITY
At 40.5 lb (18.3 kg), the ET50P combines a quick-folding frame with a 220.4 lb (100 kg) maximum load. Folded dimensions of 17.33 × 22.83 × 34.64 in (44 × 58 × 88 cm) make it easier to store in a car trunk, garage, or closet.
02 / EVERYDAY CONTROL
The 250W brushless hub motor offers three selectable forward speed modes for different riding situations. A dedicated reverse function supports careful, low-speed maneuvering in suitable spaces.
03 / FLEXIBLE CHARGING
The 280.8Wh (36V 7.8Ah) lithium-ion battery can be charged on or off the scooter. A physical key lock secures the battery and helps prevent unauthorized scooter operation.
04 / STABILITY & COMFORT
A 17.71-inch (45 cm) widened rear axle, broad footrests, and 10-inch pneumatic tires support composed handling and help soften ordinary pavement vibration. The enlarged cushioned seat and backrest add support for everyday trips.
05 / INDEPENDENT MOBILITY
The display keeps speed, trip distance, and remaining battery information visible at a glance. Straightforward controls, a compact turning footprint, and supportive seating make the ET50P a practical option for adults seeking more independent local mobility.
DESIGNED FOR REAL-WORLD MOBILITY




FOLD, STORE, AND GO

PURCHASE QUESTIONS, ANSWERED
ET50P is designed for adults who want stable three-wheel mobility, a compact folding frame, and the added comfort of an enlarged padded seat with backrest. Riders should be able to operate the controls safely and should follow all local riding rules.
ET50 uses an enlarged padded seat and weighs 37.9 lb (17.2 kg). ET50P adds a supportive backrest and weighs 40.5 lb (18.3 kg). Their motor, standard battery, forward speeds, reverse function, estimated range, and maximum load are otherwise similar.
The removable battery design makes travel planning more flexible, and UN38.3 battery transport documentation is available. In many cases, transportation may be possible, but airline and airport policies differ. You must contact your airline before travel and obtain any required permission. If you need a battery below 100Wh, an optional 94Wh battery can be ordered separately from MOOJAY.
The estimated range is 15.53–18.64 miles (25–30 km). Actual range varies with rider weight, terrain, temperature, selected speed, tire pressure, riding style, and battery condition.
A full charge takes approximately 4 hours with the supplied charger. Charging time can vary with battery condition and ambient temperature.
Yes. The standard 36V 7.8Ah battery can be unlocked and removed for convenient indoor charging, or charged while installed on the scooter.
The battery specification lists a service life of up to 5 years and more than 600 charge cycles. Actual life varies with charging habits, storage temperature, depth of discharge, frequency of use, and general care.
Yes. Compatible replacement batteries are available separately, including an optional 94Wh battery for customers who need a battery below 100Wh. Contact xgyssp1@moojay.com with your model before ordering so compatibility can be confirmed.
ET50P has three forward settings: 3 / 7 / 15 mph (5 / 11 / 24 km/h). Use a speed appropriate for the environment, surface, visibility, and local regulations.
Yes. A controlled reverse mode operates at approximately 2 mph (about 3 km/h), helping with careful low-speed positioning in suitable spaces.
The maximum rated load is 220.4 lb (100 kg), including the rider and anything carried on the scooter.
ET50P weighs 40.5 lb (18.3 kg). It measures approximately 38.98 × 22.6 × 36.42 inches (99 × 57.5 × 92.5 cm) when unfolded and 17.33 × 22.83 × 34.64 inches (44 × 58 × 88 cm) when folded. The folding frame is designed for compact storage and vehicle transport, but confirm that you can lift it safely or arrange assistance before loading it into a trunk.
ET50P includes an enlarged padded seat and integrated backrest for added support during everyday trips. Comfort depends on individual fit and riding duration, so take breaks during longer outings.
The scooter is intended for suitable firm, relatively even surfaces such as ordinary paved paths and roads where permitted. Avoid deep gravel, soft sand, mud, potholes, high curbs, flooded areas, and other surfaces that can reduce traction or stability.
The maximum rated incline is 8° under suitable conditions. Climbing performance decreases with heavier loads, low battery charge, loose surfaces, low tire pressure, and adverse weather.
Brief exposure to light rain during a short trip is generally manageable, but prolonged rain, heavy downpours, standing water, flooding, and pressure washing should be avoided. If the scooter becomes damp, switch it off, wipe it dry, and allow it to dry fully before charging or storage.
ET50P uses 10-inch pneumatic tires to help absorb ordinary pavement vibration. Check tire pressure and condition regularly, and replace damaged or excessively worn tires before riding.
The scooter uses a front power drum brake and a digital display for speed and battery information. Braking distance varies with speed, load, surface, weather, tire condition, and maintenance.
The scooter arrives approximately 90% pre-assembled. Rear-axle installation and standard pre-ride checks are required. Follow the supplied manual and confirm all fasteners, folding locks, tires, brake response, and controls before riding.
The scooter has a two-year limited product warranty and the battery has a one-year limited warranty. Consumable and wear items, including tires, are not covered for normal wear. Warranty terms exclude misuse, unauthorized modification, improper assembly, water ingress, accidents, and other non-manufacturing damage.
Returns sent without prior authorization may be rejected.
