Imagine commutes with no troublesome hills, no tired legs, and no sweating! Trek makes it a reality with their Lift+ with electric-assist. Trek starts with a low-step aluminum frame and a comfortable upright riding position, and builds it up with quality components from Shimano and Bontrager for precision shifting and braking. The magic-carpet ride is courtesy of the smooth, powerful and quiet built-in Shimano STEPS electric motor that runs off a rechargeable battery. It's a pedal-assist system, so if you pedal lightly, the range is 40 miles, and you can extend that range to 75 miles by pedaling more! It takes just four hours to recharge the down tube-mounted battery so you can go again and again!
