ECOTRIC 20" New Fat Tire Folding Electric Bike Beach Snow Bicycle ebike 500W Electric Moped Electric Mountain Bicycles … (White and Black). Purchased 10/2/20. We purchased 2 of these bikes. This one was for my wife, but unfortunately she cannot lift over the crossbar ( short legs ). So we have to sell it and get her a different one. I rode mine which is the same model just a different color and it runs fantastic! Battery will last 18 to 23 miles and speed up to 20 mph (per ecotric performance itinerary). Fat tires are well suited for sand, dirt, gravel, etc. If you’re a camper this unit folds for easy storage and weighs only 55lbs. Totally assembled. 7 speed. Disc brakes.
