Overview
Dual 4000W motors give the Tkzztks C8 an 8000W peak rating, a 52V 1352Wh removable battery for up to 100 miles of claimed range, and a top speed of 45 to 50mph in PAS level 5. It rides on 26x4.0 fat tires with four-piston hydraulic disc brakes.
The headline 100-mile range and 50mph top speed put this well above typical ebike output, closer to a light electric motorcycle than a commuter bike. One reviewer's real-world experience was closer to 15 miles between charges under hard use, so treat the range claim as a best-case ceiling rather than a daily number. A single-motor mode is included specifically to stretch range when the full dual-motor setup isn't needed.
- 8000W peak dual motor, switchable to single-motor mode
- 52V 1352Wh removable battery, IP65 rated
- 26x4.0 fat tires with lockable front suspension
- Four-piston hydraulic disc brakes
Who it's for
Fits riders who want serious off-road power and are prepared to manage a heavy, high-output ebike, including its charging routine and local rules around speeds this high. Not a fit for anyone wanting a lightweight commuter or a first ebike.
Pros and cons
- Four-piston hydraulic disc brakes for high-speed stopping power
- Single or dual-motor modes to trade power for range
- Lockable front suspension and adjustable stem
- Full lighting kit with turn signals and brake light
- Reported real-world range closer to 15 miles under hard riding
- Heavy dual-motor build isn't built for portability
- One buyer needed customer support for out-of-box issues
Performance notes
Torque and speed come from switching between single and dual-motor operation, so the 8000W peak figure only applies with both motors engaged, which is also when the battery drains fastest. The four-piston hydraulic disc brakes are sized for the extra weight and speed this bike carries versus a standard ebike setup.
