Sinch Force EZ Belt
The Sinch Force EZ Belt is a full-suspension step-through e-bike built for commuting, cycle trails and longer recreational rides. Its Bosch Performance Line Speed motor provides strong assistance up to 45km/h, while Enviolo automatic shifting and a Gates belt drive remove much of the work normally involved in changing gears and maintaining a conventional drivetrain. With a 625Wh battery, capable suspension and a full set of practical accessories, it is ready for everyday transport as well as weekend exploring.
Automatic Shifting Without Fixed Gears
The Enviolo AutomatiQ system does not use conventional numbered gears. Instead, you choose a comfortable pedalling cadence and the system continuously adjusts the gearing to help maintain it as your speed and terrain change.
This means there is no need to anticipate every climb or work through a set of gears. It is particularly helpful in traffic, on rolling cycle trails and for riders who simply want the bike to take care of shifting.
Quiet, Low-Maintenance Belt Drive
A Gates CDX carbon belt replaces the traditional chain. It runs quietly, does not require chain lubricant and avoids much of the dirt associated with a conventional drivetrain.
The belt is paired with the Enviolo internally geared rear hub, keeping the main shifting components enclosed and protected. This combination is well suited to regular commuting and year-round riding where reliability and minimal upkeep matter.
Strong Bosch Support
The Bosch Performance Line Speed motor delivers 85Nm of torque and assistance up to 45km/h. It provides plenty of help on steeper climbs, into headwinds and when the bike is carrying additional luggage.
The Bosch Kiox 300 display presents speed, battery level and ride information on a clear colour screen. Assistance settings are selected using the separate LED Remote, which is positioned within easy reach of the left grip.
Full Suspension Comfort
The RockShox 35 Silver air fork provides 120mm of travel, while the RockShox Deluxe Select+ rear shock controls 100mm of frame travel. Together, they help isolate the rider from potholes, corrugations and rough trail surfaces.
The suspension gives the Force EZ Belt a more settled feel than a rigid or front-suspension-only commuter bike. Both ends include adjustment and lockout controls, allowing the bike to be firmed up when riding on smoother roads.
Easy Step-Through Access
The low step-through frame makes getting on and off easier, particularly when the bike is carrying panniers or other luggage. A handlebar-operated dropper post lets you lower the saddle before stopping, making it easier to place your feet securely on the ground.
The swept handlebar, gel saddle and comfort grips create a relaxed riding position with good visibility in traffic and on shared paths.
Equipped for Everyday Riding
The Force EZ Belt comes with alloy mudguards, integrated lighting, a kickstand and a suspended MIK rear carrier rated to 27kg. The carrier moves with the frame rather than the rear wheel, helping protect luggage from the movement of the suspension.
The rear light includes a brake-sensor function, while the 625Wh battery can be removed for charging. Compatibility with Bosch’s PowerMore 250 Range Extender also provides an upgrade option for riders wanting additional capacity.

Why Riders Love the Sinch Force EZ Belt
The Sinch Force EZ Belt suits riders who want a powerful and comfortable e-bike without the shifting and maintenance demands of a conventional chain-driven system. Its automatic gearing makes it easy to operate, while the full-suspension frame and practical accessories make it useful well beyond the daily commute.
Effortless Shifting
Enviolo AutomatiQ adjusts the gearing continuously, helping maintain your chosen pedalling pace without requiring constant input from the rider.
Less Drivetrain Maintenance
The Gates belt does not need chain lubricant and runs cleanly and quietly. The internally geared hub also keeps the working components protected from weather and road grime.
Comfort on Rougher Surfaces
Front and rear suspension help smooth out broken seal, gravel paths, corrugations and uneven cycle trails.
Confident Braking
Shimano MT420 four-piston brakes provide the power needed to control a heavier, faster e-bike. Large 203mm and 180mm rotors improve performance on steeper or sustained descents.
Easy to Get On and Off
The step-through frame and dropper post make stops and starts more manageable, especially when the bike is carrying luggage.
Ready to Carry Gear
The suspended MIK carrier provides a stable platform for compatible panniers, baskets and other accessories.
Useful Range Options
The removable 625Wh battery provides useful capacity for daily and recreational riding, while PowerMore compatibility allows additional range to be added later.

Our Thoughts on the Sinch Force EZ Belt
The Force EZ Belt is built for riders who place comfort and ease of use ahead of saving every possible kilogram. Its combination of automatic Enviolo gearing, a Gates belt drive and Bosch assistance makes it one of the simplest bikes in the Sinch range to ride day to day.
The full-suspension frame is worthwhile for riders spending time on rough cycle trails or broken roads, while the four-piston brakes are a sensible inclusion on a bike of this weight and capability. The step-through frame and dropper post also make the bike easier to manage when stopping or carrying luggage.
At 31.5kg including the battery, it is a heavy bike to lift onto a roof rack or carry upstairs. It is best suited to riders with ground-level storage or a suitable towbar-mounted e-bike rack. If that is not an issue and you want a powerful, particularly comfortable e-bike with minimal drivetrain maintenance, the Force EZ Belt makes a strong case for itself.
