Because some ebikes are now running toothed belts, I felt it worthwhile to post the Bicycle Retailer article. If a belt can be broken on that Ikea pedal bike, it raises the possibility of ebike failures with their heavier stress loads. Just an FYI. Gates-style belts are extremely strong, Harley uses them and there is likely one spinning the camshaft in your car. In a bicycle application a belt is required to be very narrow and have lighter plies to keep it flexible which can reduce its strength rating.
