Tongsheng Mid-Drive Systems
Proudly hand-built, calibrated, and maintained across South Africa since 2014 by ebikekit.co.za. We have transformed a wide catalog of standard bicycles, heavy tandem platforms, custom recumbents, and three-wheel trikes into high-performance electric vehicles.
Designed for Natural, Continuous Power
Experience standard-setting technical integration. How Tongsheng's active hardware separates itself from cheaper cadence assistance units:
Heat Dissipation Technology
The premium motor housing is meticulously engineered using numerous, deeply-grooved aluminum cooling heatsinks. Bleeds off excess heat generated during sustained high-wattage draws to protect interior electronic controllers.
No Thermal Limiting
Cheaper e-bike motors overheat rapidly under heavy use, forcing the controller to choke down power. Tongsheng guarantees 30 plus minutes of continuous, unthrottled high-torque assistance with zero thermal power degradation.
Natural Cadence Optimization
Our responsive internal torque sensor continuously measures your physical pedaling force. Avoids bogging down during heavy climbs, keeping power flowing into your bicycle's chainline for a highly efficient trail ride.
[Bonus] FREE GEAR SENSOR INCLUDED: We bundle a premium electronic gear sensor with every Tongsheng kit at no additional upcharge. The sensor instantly cuts motor propulsion for milliseconds during gear transitions, completely preventing unnecessary wear and tear on your chain, derailleur, and cluster sprockets.
Tongsheng vs. Bafang Duel
Analyze the real-world mechanical differences based on thousands of verified online consumer reviews:
Tongsheng (Torque Sensing)
- Riding Feel: Feels like you have bionic legs. The motor amplifies your actual pedaling pressure instantly and smoothly.
- Main Advantage: Highly efficient battery usage, superior natural steering control on tight trails, and lighter total weight.
- Throttle override: Includes on-demand thumb throttle to override the active torque sensor PAS on steep hill starts.
- Durability rating: Excellent internal thermal control. Needs moderate chainline tension alignment, but has very low gear wear.
Bafang (Cadence Sensing)
- Riding Feel: Feels like a powerful scooter. Kickstarts power like an on/off switch when the pedals begin turning.
- Main Advantage: Raw, relentless straight-line speed. Ideal for effortless cargo hauling and flat road commuting.
- Throttle override: Equipped with full-coverage handlebar throttle to override cadence PAS completely.
- Durability rating: High brute torque can cause accelerated derailleur wear if shifted without care. Requires regular gear lubing.

Premium Gearing & Chainwheel Customization
Choose your mechanical drive profile. Standard Tongsheng kits ship with structural steel chainwheels engineered to preserve your gear alignments:
We supply standard 40T and 42T chainwheels. For complex offsets, a custom 40T Narrow-Wide Offset Chainring is available to align tight chainlines and prevent derailing over rocky singletrack.
Automated Brake Cutoff Safety
We adjust Tongsheng kits to match your bicycle's exact stopping infrastructure:
We offer specialized mechanical cutoff levers (for traditional rim/disc cables) and advanced magnetic sensors (for hydraulic systems). Both immediately cut motor power the instant you touch your brakes.
Bottom Bracket & Crank Fitment
Tongsheng mid-drive motors slip cleanly through your bicycle's central bottom bracket shell:
Standard models fit BSA 68mm–73mm threaded bottom brackets. Extended-spindle versions of the TSDZ2B and TSDZ8 are natively compatible with 100mm and 120mm fat tire bottom brackets.
