FAQs
The BK750 is designed to upgrade a compatible e-bike that already has an electric drive system. It is not intended to convert a non-electric bicycle into an e-bike.
Compatibility depends on your wheel setup, rear dropout width, brake type, handlebar size, battery, connectors, and existing electrical system. Review the Compatibility Guide or send Picarlo your bike model, battery label, and clear photos before ordering.
The BK750 is supplied as a matched system with the motor wheel assembly and tire pre-fitted, controller, your selected 635 or 640 display, throttle, sensor, and matching extension cable. Refer to the product configuration shown at checkout for the final contents.
The 750W BK750 is the most urban-oriented option, suited to smoother daily riding and commuting on a compatible e-bike. Final performance and legal use depend on the complete bike configuration and the rules where you ride.
Professional installation is recommended if you are not experienced with motor wheels, brakes, e-bike wiring, or electrical troubleshooting. Picarlo also offers installation support at its West Covina location for compatible projects.
Possibly. The battery must fall within the stated 36V-60V system range and match the selected controller's voltage, current output, connector, and condition requirements. Do not connect a battery until compatibility has been confirmed.
Choose the 635 if you prefer a simpler, more streamlined interface. Choose the 640 if you prefer a more detailed information layout. Both options must match the selected Picarlo controller and kit configuration.
No. Picarlo kits are sold as complete, pre-matched systems rather than as separately purchased retail components. If a component needs service after purchase, contact support for diagnosis and the available warranty or repair options.
