The ProductDome score is separate from the Amazon rating shown above: it combines the Bayesian-smoothed Amazon rating with evidence volume, tracked demand, and data quality across the 478 electric bicycles we track - how the scorecard works · full electric bicycles data report. Confidence: limited - limited rating history.Last refreshed Jun 21, 2026. Data-computed, not a hands-on test. Compiled by the ProductDome Research Team.
Overview
This is a 26 inch full-suspension electric bike with a 48V battery listed in three capacities (7.8Ah, 15.6Ah or 25Ah depending on configuration) and a claimed speed range of 20 to 40mph. It has an adjustable seat and a stated 330 lbs weight capacity.
Peak motor output is listed at 1500W with a stated top speed of 30mph in the spec bullets, though the title separately advertises up to 40mph, so treat the higher figure as configuration-dependent rather than guaranteed on every unit. The battery is described as lockable and waterproof. Reviewers were largely positive about ride quality and ease of assembly, though a couple flagged charger and reliability issues after limited use.

Who it's for
Riders who want a fat tire, full-suspension e-bike for commuting or trail riding and are comfortable with first-time e-bike setup. Less suited to buyers who need a built-in speedometer or a single, unambiguous top-speed figure.
What buyers say
From Amazon customer reviews.

On the negative side, one reviewer reported the bike breaking down within a week with no response from the company for a replacement, and another flagged a faulty charger, recommending buyers get shipping insurance.
