Electric Bike Drive Technologies
Post 1 of 15
Sourcing and comparing a number of samples from the United States and China resulted in 3 products being developed, now grossing more than $1,200,000 in retail sales and we expect the exact same products to reach $3.5M in sales over the next 12 months.There are some rules we adhered to. It must be very efficient (less than 9 watts hours per km), lithium battery technology must be safe and the vehicle must have at least a minimum 40kms range. (I say vehicle because the drive wheel can be fitted to anything that rolls)
The controller peak current is less than 15.2 amps (worst case) which prolongs the lithium battery life (to around 300~500 cycles) which reacts adversely to high current draws. The battery has a UL1642 approval combined with a brushless 36 volt planetary internal gear drive, ensuring a very high torque and low current draw and near perfect free wheeling. Using a state of the art on-bike data logger, also allows for a mass of data collection under different riding conditions. We have a number of new designs in progress including in-wheel hub sensorless-brushless controller and lithium battery management system and advanced pack.

Replying to [ABrighterDay]:.Search Google for "GPS srTrack" you will find the aeronautical web site. We do not sell electric bikes, I have been involved with a number of large companies designing, testing and specifying components for light electric vehicles. I have spent 2 years in the industry full time and function as a contractor or B2B company on a number of projects. The original products were duplicated by a number of wholesale companies in Australia and China, which is the reason that I find operating as an engineering consultant works best for me. It also allows me ensure quality parts are used ( just one poor connector can destroy an electric bike). There are a number of quality Chinese bike manufacturers that I work with for any large qualities. I have found in the past that detail is everything to Chinese manufacturing, if you make it important to the factory then it is and it will be made right the first time.
