Description

The TENWAYS CGO800S is an urban electric bike with an open step-through frame designed for commuters seeking comfort, lightness and natural pedal assistance in daily use. It features a Mivice M070 rear hub motor rated 250 W / 40 Nm, a magnetic torque sensor, a removable 36 V / 12.80 Ah (460.80 Wh) lithium-ion battery and a single-speed Gates CDN Carbon belt drive. All built on a 6061 aluminium frame with fully concealed internal cabling and STVZO certification.


Who is this bike for?

This model is particularly suited for:

  • Daily city commutes on paved roads and cycle paths
  • Riders who appreciate a step-through frame for easy mounting and dismounting
  • Those wanting natural assistance thanks to the magnetic torque sensor
  • Users seeking minimal maintenance with the Gates Carbon belt (CGO800S version)
  • Riders wanting a clean design with concealed cabling and integrated STVZO lighting
  • City riders on mostly flat to gently undulating terrain

Performance and range

The CGO800S is powered by a Mivice M070 rear hub motor delivering 250 W and up to 40 Nm of torque. Combined with a magnetic torque sensor, it provides instant response and smooth assistance that precisely matches the rider’s pedalling effort for a natural, enjoyable ride.

  • Announced range: up to 100 km
  • Maximum assisted speed: 25 km/h
  • Transmission: single-speed Gates CDN Carbon belt

Its removable 36 V / 12.80 Ah (460.80 Wh) lithium-ion battery integrates discreetly into the downtube to preserve the frame’s clean lines. Removability allows easy indoor charging without moving the bike — ideal for apartments or offices.


Design and comfort

The CGO800S is built on a 6061 aluminium open-frame with an SR SUNTOUR suspended front fork that absorbs road imperfections for greater comfort on urban surfaces. Its net weight of 19 kg (battery included, without accessories) makes it manoeuvrable and easy to transport.

CST puncture-resistant 700×48C tyres provide a generous contact patch for stability and effective vibration damping on city asphalt. The raised handlebar ensures an upright, comfortable riding position with smooth, precise steering.

TEKTRO hydraulic disc brakes deliver precise, progressive stopping power in all conditions. STVZO-compliant integrated lighting (front headlight and rear light) ensures legal visibility for day and night rides. Fully concealed cabling enhances the sleek aesthetics and durability. The Royal saddle adds superior daily comfort.

Weaknesses

❌ Single-speed transmission — less suitable for steep hills (see CGO800 Plus for inclines)
❌ Net weight of 19 kg — heavier than the CGO600 Pro (16 kg)
❌ Maximum load 145 kg (bike weight included)
❌ Mudguards, kickstand and rear rack not included as standard (optional accessories or newsletter subscription)
❌ One size only — may not suit riders outside the 1.55–1.90 m range


Comparison and positioning

The TENWAYS CGO800S stands out in the open-frame urban e-bike category with its larger 460.80 Wh battery (+27% vs previous generation), SR SUNTOUR suspended fork and magnetic torque sensor delivering a particularly refined riding experience. It targets urban riders who value comfort, design and reliability on flat terrain.

Compared with the TENWAYS CGO600 Pro, it offers more battery capacity and front suspension comfort but weighs 3 kg more (19 kg vs 16 kg). Choose the CGO800 Plus (chain + Shimano Claris 8-speed, TENWAYS C9 motor 250 W / 45 Nm) if you regularly tackle moderate urban slopes.


This bike is for you if:

✔ you mainly ride in the city on flat or gently rolling terrain
✔ you appreciate a step-through frame for easy on/off
✔ you want zero-maintenance Gates Carbon belt drive
✔ you seek natural assistance via torque sensor
✔ you want front suspension for greater urban comfort
✔ you want a dedicated app to track your rides


This bike is NOT for you if:

❌ you live in a very hilly city needing multiple gears (prefer CGO800 Plus)
❌ you want the lightest model in the Tenways range (prefer CGO600 Pro at 16 kg)
❌ you need a rear rack included as standard
❌ you fall outside the recommended height range (1.55–1.90 m)
❌ you exceed the maximum authorised load (145 kg including bike weight)
