8000W Electric Bike Kit

8000W electric bike kit, centered on the QS273 V3 Spoke Hub Motor, this kit stands out as a turnkey solution for enthusiasts and builders looking to transform standard two-wheelers into high-performance electric machines
Paired with industry - trusted components like the Votol EM200 - 2 sine wave controller and user - friendly interfaces, this kit balances raw power, durability, and ease of installation—catering to electric motorcycles, high - power e - bikes, and custom builds.

The 8000W Electric Bike Kit is designed to eliminate compatibility headaches and streamline the conversion process:

QS273 8000W V3 E - Motorcycle Spoke Hub Motor: The kit’s powerhouse, featuring a 200mm dropout (compatible with 17 - 26inch rims for mopeds and e - bikes), dual Hall sensors with waterproof connectors (IP54), and a max torque of ≥350N.m. It operates at 72V (48V - 96V optional) and hits a default top speed of 100KPH (120KPH customizable). With an aluminum stator core and 16 pole pairs, it delivers 85 - 92% efficiency while weighing 24.5kg (G.W.).

Votol EM200 - 2SP Sine Wave Controller, a compact, IP67 - waterproof controller built for 4 - 8kW motors. It uses imported materials and an aluminum substrate design to reduce temperature rise, with a rated current of 200A, peak current of 600A (short bursts), and flux weakening for enhanced speed control. Its max efficiency reaches ≥92%, ensuring smooth power delivery.

DKD LCD Speedometer supports both CAN - BUS and LIN communication, displaying critical data like gear status (D/N/R/P/S), battery current (×5/×10), speed, and mileage. A LIN - version option is available for non - CAN - BUS batteries to avoid false low - power readings.

Z6 Throttle with Combination Switch, a durable ABS/PVC half - twist throttle (22mm inner diameter) with IPX6 waterproofing. It includes reverse, parking (throttle on/off), 3 - gear slide switches, an S/boost button, and controls for lights/horns—seamlessly matching the Votol controller.

For a plug - and - play experience, the kit adds a Vehicle Wiring Harness  with essential accessories: 4p 72V 40A relay, flasher, 72V - 12V 10A DC converter, and electric lock ignition. This eliminates the need for sourcing separate wiring parts, cutting down installation time.

The 8000W motor, when paired with a 72V battery, delivers a default 100KPH (120KPH optional) on flat terrain and handles steep climbs effortlessly—thanks to its ≥350N.m torque. Test reports show it maintains 83.5% efficiency at rated load (145.3N.m, 951rpm), ensuring minimal energy waste.

The rear - mountable hub motor eliminates the need for gearboxes, transmission shafts, or clutches, freeing up space for larger batteries to extend range.

Key components boast robust protection—IP54 for the motor, IP67 for the controller, and IPX6 for the throttle—making the kit suitable for all - weather riding.

The system supports regenerative braking, recapturing energy during deceleration to boost battery life and reduce brake wear.
