Thesis Statement

Affordable E-bike's main cause is to create an affordable alternative to a car, for people who either cannot afford a car or would like to spend less money on transportation. The goal is to create a bike that would allow commuters to go further and faster, without breaking the bank. This is done by combining the attractive aspect of a single-speed bike (cheap maintenance and simplicity) with the positives of an electric bike (longer distance with less effort).

Sketches

These are the first initial sketches that we made

Prototypes

Testing pieces

1.) Bracket should fit snug on any bike with a beam between the two rear frame pieces.

2.) If the motor bracket fits, the motor will fit.

3.) Will be adaptable for any bike with the hole between the frame in the back

4.) Would be able to drive which ever gear you choose.

Observations

Used Bike

We got a free bike from a coach, and ended up fixing it up to make it ridable, and work for our project. We replaced the chain, freewheel, 2 spokes on the wheel, driveside crank arm, bar tape and fixed two flats.
