BMC Motors 

We consider BMC to be the best geared hub motor available.

Our Thunderbolt kit price of $1,764.00 includes CA-DP V2.3, 12.5 Ah 37V battery, 4 amp charger, BMC motor laced with 13 gauge spokes in a 20" (non-disk) silver wheel, throttle, BMC controller, and case hardened steel torque arm.  

I suppose one big advantage we have is that the owner of BMC lives just down the street, and any repairs, which are infrequent, are performed right here in Chatsworth, California. The BMC motor is one the sturdiest and most powerful-geared hub motors on the market, and an elegant solution for converting your bike.

Personally, I love this motor for its size, weight and hill climbing ability. You know a front hub option is also available; the advantage being less wear and tear on the gears and chain. It also allows you to use an internally geared hub, which I find to be an elegant solution.

It is the ideal combination of torque and speed. This lightweight, high-performance motor is one of the best and most refined E-bike conversion solutions available today. Paired with the right components it can turn virtually any bike into a high-end E-bike.

The latest release - the V4, is an improved version of the popular V2 model. It has amazing hill climbing power and is capable of impressive top speeds considering its external diameter of less than 8 inches (170mm) and weighs only 10 pounds (4.5kg).

The internal 5:1 planetary gearbox allows the motor to spin faster than the wheel, significantly increasing efficiency and torque compared with gearless (direct drive) hub motors.

BMC motor composite gears are far superior to nylon gears commonly used on lower power geared hub motors, and are capable of handling power exceeding 1000 Watts. They can be expected to last at least 5-10 thousand miles without any maintenance.

Top speed in 26" wheel: 
29-30mph @ 52V 25A

If you like pedaling with the motor off, BMC is the right choice for you. A built-in clutch/freewheel disengages the motor from the wheel when it's not powered, which eliminates motor drag.

Axle seals protect the motor from dust and moisture.

This motor accepts standard 6 hole disc brake rotor, and a standard freewheel cog set, 7 or less speed freewheels recommended, 8, 9, and 10 speed freewheels will work with a spacer washer which is included.

The pricing you see below at $990 is for a front or rear motor and controller.
