UM4+ is a rugged utility electric bike built with simple, long-life performance parts that make it easy to make this bike a part of your everyday routing. Internal 7-speed gearing, a low-maintenance Gates belt drive system, a powerful Bosch motor for speeds up to 25 km/h, a rear rack battery and hydraulic disc brakes give it the capability to take on daily commutes, shopping runs and more!

You're a daily rider looking for a rugged utility bike you can depend on for everything. You're looking for a no-hassle e-bike with durable parts that won't wear out, even when they're ridden hard.

An Alpha Aluminium frame, a powerful Bosch Active Line Plus (250 W, 50 Nm) motor for speeds up to 25 km/h, a Walk Assist feature and your choice of a 300 Wh, 400 Wh or 500 Wh battery. Plus, internal 7-speed shifting, a durable and low-maintenance Gates belt drive system, hydraulic disc brakes for all-weather stopping power, puncture-resistant tyres, a rack, mudguards, lights, a U-lock, lock-on grips and an adjustable Blendr-compatible stem.

If you value dependability in your utility bike, UM4+ is for you. It's built with durable parts, but it's also trimmed with touchpoints that feel great when you're riding day after day.

- Smooth welds add to the aluminium frame's sleek looks
