·         We ran into problems regarding transmission of the signal from the force sensor on the pedals, so we dropped that in favor of controlling the motor based on the speed at which the rider is pedaling.  The motor will pulse in rhythm with the rider’s pedaling, turning on at the beginning of a stroke and turning off again near the end.  This system should allow the user to control the motor simply by riding the bike as they normally would.  The system will work by adding a magnet to the crank arm of the pedals and detecting its motion using Hall effect sensors mounted on the chain guard.

We submitted our budget allocation to the dean. We are waiting to hear back to see if our budget passed or not.

 
To prevent power loss from the conversion of kinetic energy into electrical energy, and then back into kinetic energy we may use a mechanical regenerative braking system. This system would store the energy in springs instead of generating electricity to store in the battery.
 
Mounting new parts on our bicycle is one of out major challenges. Finding a way to mount parts that will fit almost any bicycle is not easy. Instead of trying to clamp mounting brackets around the bicycle frame, we had the idea to run a nut and bolt through the frame. This would help fit all frames, and provide a very sturdy mount.
 
Welcome to the Power Assisted Bicycle Kit Blog. This is our senior project at The College of New Jersey. By the end of the year we hope to have a working and efficient power assisted bicycle kit. We hope to provide updates here about our project.
