 ELECTRIC BIKE The all-new Transend E+ combines Class 0 00mph maximum assist with the smooth, easy shifting of the Shimano Nexus internally geared hub and wide, shock absorbing tires for a unique, well-priced transportation solution. The SyncDrive Life motor from Yamaha delivers six levels of assist for smooth acceleration while the frame-integrated battery pack provides a clean, stealth appearance. Momentum is a sibling brand of Giant, and like other Giant e-bikes now includes an automatic assist mode, which sets the assist level for you based on what you need to most smoothly climb the hills.
