Overview
Jasion's EB5 Ultra is a fat tire electric mountain bike built around a 2500W peak motor, a 52V 20Ah (1040Wh) battery and dual suspension. It targets riders who want strong hill-climbing power and long range for mixed street, trail and off-road use.
One reviewer describes this as a class 3 e-bike, meaning speed and use rules vary by state, so check local regulations before riding it on public roads or trails. The 330 lb payload rating and rear rack point toward a bike meant to carry cargo as well as a rider. A recurring caveat from owners is that seat height adjustment has real limits, so taller or shorter riders should weigh frame geometry against their own height before buying.
- 2500W peak motor, roughly 75N.m torque
- 52V 20Ah (1040Wh) removable battery
- 26x4 inch fat tires with dual suspension
- Hydraulic disc brakes, headlight and brake-activated tail light
Who it's for
Suits adults who want an electric mountain bike with real hill-climbing torque (about 75N.m) and enough range for commuting or trail rides without daily charging. Less suited to riders near the edges of typical height ranges, since seat adjustment has limits.
Pros and cons
- 52V 20Ah battery rated up to 70 miles
- Dual suspension and hydraulic disc brakes
- Rear rack and fenders included for commuting
- Reported easy at-home assembly
- Seat and frame have limited height adjustment range
- No stated liner in the fat tires against punctures
Performance notes
The 2500W peak motor and roughly 75N.m of torque are paired with a 7-speed drivetrain and 5-level pedal assist, so power delivery can be tuned from light assist to full throttle. The 160mm rear shock and front fork are meant to absorb impact on rough terrain, while the 26x4 inch tires add grip on sand, snow and gravel. Hydraulic disc brakes plus a brake-activated tail light are aimed at stopping power and visibility rather than top speed alone.

Frequently asked questions
What tools do I need to assemble the Jasion EB5 Ultra?
The included kit covers most of it, though buyers report a socket set (10mm, 13mm, 15mm) makes attaching the front tire, fenders, rack and handlebars easier.
How far can the EB5 Ultra go on a charge?
Jasion rates the 52V 20Ah (1040Wh) battery for up to 70 miles, though real-world range depends on terrain and pedal assist level used.
Is the EB5 Ultra suitable for taller riders?
One owner at 5 feet 11 inches found it hard to balance at stops even with the seat lowered fully, so taller riders should weigh frame geometry carefully.
