Electric Bike Journal (unit source not stated in the excerpt read) found the Onyx ST smooth and planted on river rock and sand, with strong, consistent Tektro brakes, but called the price significant (Dec 2025)

YouTubeNot scored

The YouTube pool is blank at brand level: the creator videos found review single models, and most carry Mokwheel discount links or do not say how the bike was obtained (October 2026).

AmazonNot scored

The Amazon pool is blank: MOKWHEEL-branded e-bike listings appear in Amazon search, but no listing could be read with its model, seller and review count (October 2026).

User reviewsNot scored

The retailer pool is blank: none of Walmart, Best Buy, Target, Costco, REI, Home Depot and Lowe's sells Mokwheel e-bikes, so no retailer review feed exists for this model; Dick's Sporting Goods' site was unavailable when read (October 2026).

Reviews

Trustpilot shows a 4.5 TrustScore from 569 reviews, 75% of them five-star and 11% one-star, on a claimed page that invites customers to review (July 2026).

Track record
  • The BBB rates the business F, not accredited, with 32 complaints in the last three years (October 2026).
  • A search of CPSC and Health Canada recall listings found no recall of a Mokwheel e-bike or battery (October 2026).
  • In June 2025 Mokwheel posted its own recall notice, not a CPSC recall, offering free replacement of some first-generation Scoria and Basalt ST batteries built before their UL certification was final.
