https://electricbikereview.com/pedego/20-trail-tracker/ The Pedego 20″ Trail Tracker is a sturdily built, lower speed electric bike with seven gears and throttle-only operation designed primarily for kids and youth but also a good fit for short riders. Max weight of 350 lbs, bosses in the rear for adding a rack and hauling cargo (perhaps to school?) and mid-level mechanical disc brakes providing clean powerful stops. The cockpit is clear of distractions, simple to use and less vulnerable to bumps and scrapes, a derailleur guard protects the sensitive bits, the bike is priced lower than the adult sized Trail Trackers (24” and 26” models). Two-step power up process, no room for a bottle cage, limited suspension but the tires absorb a lot of shock, shifters could be difficult for small hands to reach while riding, spectacular two year all-inclusive warranty.
