Inspiration
Being an avid biker and completing long treks in my city was great and fun the issue was that my friends couldn't keep up I figured the best way to go about fixing this problem was to give them the pedal push they needed.
What it does
3D Printing out a driver gear that fits onto the rear wheel of most mountain bikes and then attaching a drive train to said gear allows for the bike to receive pedal power through the means of a battery attached conveniently under the seat.
How I built it
3D prototyping through SolidWorks, AutoDesk and finally printing out the gears with my 3D printer allowed to create the gear pieces and brackets to attach onto my bike. The belt for the gears was founded from an old 3D Printer z-axis Motor was taken from dishwasher component Voltage provided
