Product Description

The U4 folds down for a car trunk, closet or office corner, yet still offers up to 35 miles of range, more than most compact folding e-bikes. That makes it a good fit for longer commutes or mixed train-and-ride trips.

A 500W motor reaches 19 mph. The 36V 10.4Ah battery charges in 4 to 5 hours. Wider 16 x 2.15 inch tires add stability on uneven pavement and light gravel.

Front shock absorption softens bumps, and disc brakes on both wheels handle stopping. An LED headlight is included, and max load is 264 lb.
