If you only look at one number on this page, make it this one: 2,329 ratings. Every other bike in this comparison is in the double or low triple digits. A 4.1 average from more than two thousand buyers is a fundamentally different kind of evidence than a 5.0 from nine people, and it is why the EB5 leads our US list. Amazon also stamps it #1 best seller in electric mountain bikes — that badge is Amazon's, not ours, and it is the only real sales signal the site publishes.
At $339.99 it is also the cheapest full-size e-bike here by a wide margin, and the spec sheet explains why it sells: a removable 500 Wh battery, a 7-speed derailleur, dual disc brakes, a front fork and 26-inch puncture-resistant tires. At 49.6 lb it is genuinely light for this price bracket — most sub-$500 e-bikes are steel anchors well past 60 lb. Buyers repeatedly mention assembly taking 15 to 30 minutes out of the box.
What Jasion does not tell you matters. The listing advertises a "1,000 W peak" motor and never once states nominal wattage. Peak is a marketing number — it is what the motor pulls for a few seconds on a hill. Nominal is the number that the federal 750 W definition of a low-speed electric bicycle is written around, and it is the number your state's law cares about. We have left nominal blank on the spec table instead of inventing it. In practice the bike has a throttle and tops out at 20 mph, which puts it squarely in Class 2 behavior, and Class 2 is legal on most bike paths in most states. But if you need the paperwork to say so, ask Jasion directly before you buy.
The range claim of 25 to 40 miles deserves the same skepticism it deserves everywhere: 40 miles is at the lowest assist setting, on flat ground, with a light rider. Plan around the low end.
The 4.1 rather than a 4.5 is the honest cost of selling this many units at this price. Read the one-star reviews before you buy — they cluster around shipping damage and warranty response, not around how the bike rides.

A summary of the reviews published on Amazon.com as of 2026-08-21.
4.1 out of 5 from 2,329 ratings — the largest sample on this site by a factor of four. The recurring praise is fast assembly, real hill-climbing help and battery life that matches the claim. The recurring complaint is not about riding: it is about boxes arriving damaged and about how slowly warranty claims move. Several five-star reviews explicitly note the bike arrived roughly 75% charged and needed about 15 minutes of work.
