The short version

  • Best for upright urban riding, frequent stops, flatter commuting and riders who value easy mounting
  • Mivice M070 250W rear-hub motor with a torque sensor
  • 374Wh removable battery; the Lavender Purple specification may use a larger 460.8Wh pack
  • Main trade-off: One gear is a real limit on steeper routes
01

Where the CGO800S fits

A relaxed step-through city e-bike with a quiet hub motor, belt drive, broad tyres and front suspension. It targets comfort and easy access rather than sporty handling or steep-terrain gearing.

At a researched UK list price of £1,399, the important comparison is not simply motor power. Frame access, total mass, gearing, battery energy, service access and the regular route decide whether this step-through belt-drive city bike is good value. Prices, colours and component substitutions can change, so the live Tenways page remains the final pre-purchase check.

Motor, torque and hill performance

Tenways specifies the CGO800S with a Mivice M070 250W rear-hub motor with a torque sensor and 40Nm of maximum torque. A torque sensor measures pedal pressure and should add support in proportion to the rider’s input, which generally feels more natural than a simple rotation sensor. UK-compliant assistance must progressively cut out by 15.5mph; the motor does not make this a powered vehicle above that threshold.

Motor location and gearing matter as much as the headline torque. This bike uses single-speed Gates Carbon Drive belt. On a hill, the rider should choose an appropriate mechanical ratio where one is available, keep a smooth cadence and avoid forcing the drivetrain in an excessively high gear. One gear is a real limit on steeper routes

Battery, charging and realistic range

The listed battery is a 374Wh removable battery; the Lavender Purple specification may use a larger 460.8Wh pack. Tenways claims up to 100km under favourable test conditions, but that is an upper-limit marketing figure rather than a promise for every journey. Cold weather, hills, repeated starts, soft tyres, luggage, rider mass and high assistance can all reduce distance substantially.

Compare batteries in watt-hours, not only in kilometres. A sensible owner plans around the hardest regular return trip, keeps a reserve for detours and battery ageing, and charges with the supplied compatible charger in a dry place with a working smoke alarm. Stop using a battery that is swollen, damaged, unusually hot or has been immersed.

Ride, comfort and handling

The CGO800S trades the CGO600’s taut, light character for a calmer and more upright position. Wide tyres and a short-travel suspension fork take the sting out of patched streets, while the low frame makes repeated mounting at junctions easier.

Road.cc found it practical, smooth and nearly silent in normal city use. Ars Technica framed it as a utility-first machine: that is a useful description because the appeal lies in arriving comfortably with little drivetrain fuss, not in providing a lively multi-gear ride.

Equipment and everyday practicality

The core equipment is Tektro hydraulic disc brakes, 700×48C CST puncture-resistant tyres and a SR Suntour suspension fork. Listed weight is about 19kg net and 23kg with fitted equipment; the permissible load is 145kg. Tenways positions the fit for riders around approximately 155–190cm, but height is only a starting point. Reach, saddle position, stand-over clearance and control access need checking on the actual bicycle.

The belt should keep trouser legs cleaner and reduces routine drivetrain work. The single-speed layout also removes a derailleur, but the suspension fork, hydraulic brakes and electrical system still need inspection and service.

Battery capacity differs by colour or edition, so compare watt-hours rather than relying on the shared model name. A larger pack can add useful margin, but rider mass, temperature, hills, assistance level and tyre pressure will decide actual distance.

What independent reviewers are saying

Independent commentary is broadly useful when it describes repeated ride characteristics rather than simply repeating a specification. For the CGO800S, the published themes are reflected in the source notes below. RideIn has not presented this specification-led review as a laboratory test, and a new or lightly covered model has a smaller evidence base.

Strengths and disadvantages

The model’s attractions and limitations are best read together. A feature that benefits one route can be a compromise on another, so a decision should start with terrain, storage, carrying and local servicing rather than appearance alone.

  • Strength: Accessible step-through frame
  • Strength: Quiet belt-drive operation
  • Strength: Wide tyres and suspension improve poor-road comfort
  • Strength: Natural torque-sensor response
  • Disadvantage: One gear is a real limit on steeper routes
  • Disadvantage: More weight than the CGO600 family
  • Disadvantage: Suspension adds service needs and does not replace good tyre setup
08

Ownership, warranty and service checks

Tenways’ published UK warranty gives the frame and rigid fork longer coverage than most electrical components, while motors, batteries, controllers and displays generally have shorter defined periods. Consumables, crash damage, incorrect assembly, unauthorised modification and normal battery ageing are treated differently. Read the current terms rather than assuming every fault is covered.

Before ordering the CGO800S, identify the retailer or service partner responsible for assembly, diagnostics and warranty labour. Check the frame number, charger marking, battery keys, firmware or app requirements and availability of model-specific spares. A local test ride should include a hill, repeated starts, hard controlled braking and low-speed turns.

RideIn verdict

The CGO800S is a convincing comfort commuter for flatter areas. If the route is hilly, the CGO800 Plus adds gears and torque at the cost of extra weight, chain maintenance and price.

The best match is upright urban riding, frequent stops, flatter commuting and riders who value easy mounting. It is a weaker match when its listed disadvantages collide with a non-negotiable part of the journey.
