Description

Step-over aluminium frame
26 x 4.0 fat tyres
Torque & cadence sensor
Shimano 7-speed gearing

Cyrusher Zenith Electric Bike is a UK-spec step-over fat tyre electric bike built for riders who want a more planted, more rigid feel than a step-through frame. With a road-legal 250W motor, a Samsung 21700 52V 15Ah battery and wide 26 x 4.0 tyres, the Zenith is designed for confident riding across roads, gravel, towpaths and light trails.

Why the Cyrusher Zenith stands out

Step-over aluminium frame for a sporty, stable ride feel
26 x 4.0 Chaoyang fat tyres for extra grip, comfort and confidence
Torque & cadence sensor support for smoother, more natural pedal assist
Samsung 21700 52V 15Ah (780Wh) battery with up to 60 miles claimed range
Shimano 7-speed gearing for easier climbing and better control over mixed terrain
Logan hydraulic disc brakes for stronger, more consistent stopping power

Built for more than smooth tarmac

The Zenith suits riders who want one bike for weekday commuting and weekend exploring. The wide tyres help take the sting out of rougher surfaces, while the front suspension fork adds comfort on broken roads, canal paths and compact trails. If you prefer the feel of a classic crossbar frame over a step-through design, the Zenith is the more confident and purposeful option.

Natural assist with practical everyday spec

Cyrusher positions the Zenith as the step-over alternative to the Aura, with a more rigid frame shape and the same easy-to-live-with 250W road-legal setup. The colour LCD display keeps key ride data clear at a glance, and the Shimano 1x7 drivetrain gives you a wider spread of gears for inclines, flatter stretches and stop-start urban riding.

Why buy from TrailSurge UK?

Order from TrailSurge for UK support, finance options, Cycle2Work compatibility and collection from our Nuneaton location. You can also browse more Cyrusher electric bikes, compare other road legal electric bikes, or view the product manual and assembly guides before ordering.

Range figures are manufacturer claimed. Real-world range varies with assist level, rider weight, terrain, tyre pressure, weather and stop-start riding.
