Description
Quick Summary The Cyrusher Nova is a sleek step-through city e-bike designed for commuting, leisure, and practical everyday use. With its road-legal 250W motor, torque sensor and high-capacity battery, it delivers smooth performance, comfort, and reliability for both short and long-distance rides.
Smooth Power Delivery Powered by a 250W brushless rear hub motor, the Nova provides smooth pedal assistance up to 25km/h, fully compliant with UK and EU regulations. Its torque sensor combined with a Shimano 8-speed drivetrain makes every ride feel natural and efficient.
Comfort & Control The step-through aluminium alloy frame ensures easy mounting, while 20” x 3.0” fat tyres offer excellent grip and stability across city streets and cycle paths. A front suspension fork with preload adjustment softens bumps, and Shimano hydraulic disc brakes deliver powerful and reliable stopping performance.
Smart Battery System The Nova is fitted with a removable 36V 15Ah lithium-ion battery, expandable to 20Ah, providing up to 90km of assisted range depending on terrain and riding style. Charging takes approximately 5–6 hours, making it suitable for daily commuting.
Tech You Can Trust A full-colour LCD display keeps you updated on PAS level, speed, trip distance, and battery life. Integrated LED front and rear lighting, including a brake-activated tail light, ensures visibility and safety in all conditions.
Built for Everyday Use Weighing just 25.6kg and with a maximum load of 160kg, the Nova is practical for both riders and cargo. Its step-through frame design, rear rack, and comfort-focused build make it an ideal choice for urban commuters and leisure riders alike.

Assembly Information
Assembly Video
Watch the assembly guide below before first setup.
The Nova uses a removable 36V 15Ah battery, with Cyrusher quoting up to 90 km (56 miles) per charge.
Charging typically takes around 5–6 hours. Real range will vary with hills, assist level, rider weight, tyre pressure and temperature.
For normal city hills, yes. The 250W rear hub motor delivers up to 42 Nm, while the torque sensor and Shimano 8-speed gearing help the assistance feel smooth and controlled on gradients.
Yes. The 20 x 3.0 tyres give more cushioning and stability than narrow city tyres.
Combined with the front suspension fork and hydraulic disc brakes, they work well on broken tarmac, cycle paths and light gravel.
The Cyrusher Nova Electric Bike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.
The Cyrusher Nova Electric Bike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.
Everything about this bike feels solid. Great comfort, smooth assist and it handles well on varied routes. Couldn’t be happier.
