Hydraulics

The hydraulic disc brakes are easy to modulate and have good feel, but I think I'd rather have easier-to-maintain mechanical stoppers. Read full review

Quick release

Wheels and tire

At 2.35 inches wide, these tires contribute to the e-bike's smooth ride, but also add a bit of off-road ridability. The 24-inch wheels that they're wrapped around are smaller than your average road wheel, but satisfyingly maneuverable. Read full review

Internal cabling

Most of the cabling that you'll find on the Alva+ is routed internally, through the aluminum Y-frame, so there's not much to catch on. Read full review
