VARUN sell electric mountain bikes direct and through Amazon at the affordable end of the market. The M27-1 listed here is tagged UK road legal under the EAPC rules, so it runs a 250 W continuous-rated motor with the assistance cutting out at 15.5 mph and needs no registration, tax or insurance to ride on public roads. As with most bikes at this price, the frame and motor are the strong points and the savings tend to show in the gearing, brakes and finishing kit.
