Could your employer help you spread the cost? Cycle to Work

Many UK employees can get an e-bike through a Cycle to Work scheme, spreading the cost through payroll and potentially saving on tax and National Insurance.

Not sure if your employer offers one? It may be worth asking HR — many people are eligible without realising.

🔧 Bike setup & first ride Boxed delivery — some final assembly and safety checks needed.

Your bike will arrive boxed and approximately 80% assembled. Some final assembly, adjustment and safety checks will be needed before your first ride.

Depending on the model, this may include fitting or checking the handlebars, stem, pedals or wheels, checking tyre seating and pressures, adjusting brakes and gears, and checking other safety-critical components.

Please follow the manufacturer's instructions supplied with your bike and make sure all required assembly, adjustments and safety checks have been completed correctly before riding.

If you're not confident carrying out the setup or checks yourself, we recommend asking a competent bicycle mechanic or suitably trained cycle professional to help.

You're responsible for making sure the bike is correctly assembled and safe to ride before first use. Problems caused or contributed to by incorrect assembly, adjustment or missed safety checks may not be covered as product faults.

WHY THIS MODEL IS WORTH A CLOSER LOOK

What are you actually paying for?

The Zenith is a big-battery, fat-tyre step-over e-bike for riders who favour a traditional crossbar and want flexibility across roads and recreational tracks. The value lies in its power storage, riding response and useful braking components.

A generous removable 780Wh battery

With 52V and 15Ah capacity, the 780Wh battery supports longer days out without promising a fixed distance. The manufacturer quotes up to 60 miles; conditions and assistance level make a substantial difference in practice.

Pedal support with more nuance

Torque and cadence sensing provide a more adaptable riding response than entry-level cadence sensing alone. Shimano 7-speed gearing lets riders choose comfortable pedal ratios on changing gradients.

Fat-tyre grip and hydraulic stopping

Chaoyang 26 × 4-inch tyres suit mixed surfaces, while Logan hydraulic disc brakes offer measured control. A coil-spring front suspension fork helps reduce everyday bumps and an integrated headlight and brake light provide useful visibility.

🔧 Assembly, servicing & aftercare

If your bike arrives boxed or partially assembled, any remaining assembly, adjustment and safety checks need to be completed correctly before you ride it. Please follow the manufacturer's instructions supplied with your bike.

Delivery & Timing

Bikes are usually delivered to most UK mainland addresses within 3–7 working days of order placement. Northern Ireland, Northern Scotland and the Channel Islands may take longer and may incur additional shipping fees.

Bikes are delivered boxed and around 80% assembled. Some final assembly, adjustment and safety checks will therefore be needed before your first ride. Depending on the model, this may include fitting or checking the handlebars, stem, pedals or wheels, checking tyre seating and pressures, adjusting brakes and gears, and checking spokes, fasteners and other safety-critical components.

Please follow the manufacturer's instructions supplied with your bike and make sure everything is correctly assembled, adjusted and secure before riding. If you're not confident carrying out the setup or checks yourself, we recommend asking a competent bicycle mechanic or suitably trained cycle professional to help.

Orders are processed within 1–2 working days before dispatch. Delivery times may be slightly longer for made-to-order, fully built or other specialist delivery options.

Returns & Refunds

We offer 28-day returns, subject to our returns policy. If you wish to return your bike, please contact us first so we can explain the process and any applicable return transport arrangements.

If an item is faulty, damaged or incorrect, your statutory consumer rights remain unaffected.

Overall Summary

This all-terrain electric bike is widely praised for its exceptional power and hill-climbing capabilities, particularly noting a high torque output that exceeds typical expectations for its legal motor class. Users appreciate the dual-sensor system, which offers a customizable riding experience between a natural, responsive pedal feel and effortless cruising. The sturdy frame and large fat tires provide a stable and commanding presence that handles both urban streets and muddy trails with ease. While the ride quality is highly regarded for its smoothness and stability, common feedback highlights the bike's substantial weight and the omission of certain standard accessories. Safety is frequently cited as a strong point, with reviewers consistently mentioning the responsiveness of the hydraulic braking system and the high visibility of the lighting.

What Customers Love

  • High Torque Output: The motor delivers a remarkable 80-95 Nm of torque, allowing it to conquer steep inclines and challenging off-road conditions with significantly less effort than competitors.
  • Dual Sensor System: Riders can switch seamlessly between torque and cadence sensors, providing the flexibility to choose between a responsive, natural pedaling feel and a more relaxed cruise.
  • Reliable Hydraulic Brakes: The high-quality hydraulic disc brakes offer powerful and consistent stopping force, ensuring rider confidence and safety in various weather and terrain conditions.
  • Robust All-Terrain Design: A sturdy step-over frame paired with 4-inch fat tires ensures excellent stability and comfort, making it a versatile explorer for both city commutes and rugged trails.

Cons

  • Substantial Overall Weight: Weighing approximately 34kg, it is difficult to maneuver when stationary and very challenging to pedal comfortably without motor assistance.
  • Missing Standard Equipment: Users have pointed out the lack of a front mudguard and an integrated electric horn, which are often expected features at this price point.
  • Wider Turning Circle: Due to its large 26-inch wheels and overall frame size, the bike has a noticeably larger turning radius than traditional bicycles, making tight turns more difficult.
  • Firm Stock Seat: Some reviewers found the original saddle to be quite stiff, suggesting that riders planning long-distance trips may want to consider a more cushioned replacement.
