Features

• High-Torque PMDC Gear Motor: Features an internal 1:9.78 reduction ratio to supply a commanding 9 N.m of continuous torque, perfect for inclines and heavy payloads.
• Smart Power Micro-Controller: Housed in a heat-dissipating aluminum shell that manages up to 20A peak loads and triggers auto-cutoff at 20.5V to protect the battery.
• Safety Auto-Cut Braking Levers: Upgraded mechanical levers immediately isolate electrical current to the motor upon braking to ensure short, safe stopping steps.
• Dual-Purpose Headlight & Horn: Single handlebar-mounted modular housing incorporates a low-amp roadway illumination LED light and an emergency traffic horn.
• Turnkey Mechanical Hardware: Composed of a heavy-duty structural steel mounting bracket plate, a 9-tooth 1/8" drive sprocket, a matching drive chain, a freewheel, and an adapter.
• Charger-Excluded Value Option: Designed purposefully for custom builders who already own a 24V charging platform, cutting down setup redundancy.

Applications

• Standard Bicycle Electrification: Upgrading standard everyday commuter road cycles, single-speed city bikes, or mountain bikes into lightweight e-bikes.
• Custom DIY EV Prototype Projects: Powering small neighborhood electric vehicles, customized kids' scooters, balance triads, or custom school engineering models.
• Low-Cost Local Delivery Transits: Augmenting the hauling power of traditional cargo distribution cycles operated by food, courier, or local delivery riders.
• Daily Economical Intercity Commutes: Providing a budget-friendly transit alternative to reduce fuel expenses via high-efficiency electric power.

Usage

• Position and bolt the heavy-duty steel mounting plate onto the bicycle frame stay alignment tabs using the included structural fasteners.
• Anchor the 24V PMDC gear reduction motor firmly to the bracket plate and loop the provided drive chain over the 9-tooth sprocket and the wheel-mounted freewheel adapter.
• Swap the stock handlebar grips and brake handles out for the responsive linear twist throttle set and the electrical auto-cut safety brake levers.
• Align and snap the multi-pin terminal plug clusters from your 24V battery source (not included), motor, throttle handle, key switch, and headlight directly into their marked controller slots.
• Ensure all lines are clear of moving mechanisms, engage the main ignition key lock to initialize electric distribution, and turn the throttle to ride.
