Swap traffic jams for tail-wind thrills. The Jasion EB5 pairs a 350 W rear-hub brushless motor with a removable 36 V 10 Ah (360 Wh) lithium battery, delivering up to 40 mi / 64 km of real-world range and a top speed of 20 mph / 32 km h⁻¹. A back-lit LCD keeps speed, distance and PAS level clear in any light.
The high-carbon-steel frame tips the scales at just 49.6 lb / 22.5 kg yet carries riders up to 264 lb / 120 kg. Front-fork suspension, puncture-resistant 26 × 1.95″ (660 × 50 mm) tyres and dual mechanical disc brakes tame rough city streets and light trails alike.

In the second week itself, all the spokes on the rear wheel came loose.
Thanks to Amazon’s service team—they tried to help by contacting Jasion. Jasion did help by refunding the repair cost.
However, the tires are the worst I’ve ever experienced. They get punctured easily, and most of the grip is already gone. I’ve had a flat tire twice already.
They claim the range goes up to 40 miles, but in reality, it only gives 20–23 miles at most, even on the lowest pedal-assist setting. On the highest setting, expect just 10 miles of range.
Update 2.0
Jasion bike reached out regarding and offered to send replacement of tire
I think the value for what you are getting is a solid bet, I purchased this with a sale going and paid $340, which to me is a fair price.
It gets four stars for me because the seat, while functional, is super uncomfortable and for a daily commuter you’ll probably want to upgrade to a different seat - I simply took the seat off my other bike and switched the bolts out to make it look clean for the assembly. Super easy to assemble out of the box, came with a full charge, also mine came over a week early for delivery - so that was awesome too.
I’ve been riding the bike over the last week, outside of the seat being uncomfortable, the handle bars seem to sit a little low for me - I am 5’11, so if you’re near that height I’d look into an adapter so you can have your handle bars ride a bit more comfortably for your height. After riding around town (at full throttle) for a little over 4 miles, my charge was at the halfway point - I’m at 190 lbs, impressed me in terms of its ability to haul me around, going up the steep hills in my area has also became significantly easier with this bike. Another thing of note is the battery indicator, as it goes past half battery the indicator will read various charge levels, jumping from one bar and sometimes back up to half charge. So far it hasn’t been an issue, I’d like to have the option to purchase another battery but haven’t seen any options for this specific bike - thought that was strange, there is probably an after market option out there. Outside of these specific things, the bike rides and handles really well, again I think the value of what you’re getting is solid, you can modify the bike as you go if you wanted to improve upon it, definitely have a bike seat in your shopping list if you buy this - solid bike!
Get bright or reflective helmet, jacket, pants, and backpack if you intend to go out in low light or dark conditions. You will be going 2-3 times faster for half as much effort, people on the road won’t be expecting you to be going this fast on the sidewalk. Parking lots, driveways, and street crossing is extra dangerous.
One of the pedals broke off, after my 1st fall/crash near the train tracks. My mountain bike took 20 years of similar crashes/falls to break a pedal.
The chain began rusting after 3 weeks of use. The chain on my 30 year old mountain bike that I barely take care of, is still rust free.
As of today, when I use pedal assist mode 3, the chain slips, but does not slip when only using the motor.
I do not drive. I relied on my mountain bike to get around my whole life until I got this on Thanksgiving. If Jasion were to use a higher quality chain and pedals, I think this bike would be perfect, it is however, very much worth its price.
Final Verdict? It's a good bike produced by a good company. Just make sure you have everything you need to go over each and every screw on it & tighten down All of them before you even take it for a test ride.
