When it comes to observing the schema of upgrading bicycles into a hybrid model, the existing model usually costs hundreds of dollars and more than one hour of installation since it requires the process of replacing a wheel or even purchasing a new bicycle. But in fact, it was not necessary to remove the original wheel because the key to achieve power drive could be taken as an external function added to the primitive bike. Under the conditions of retaining applicability and safety that transportation should never get rid of, this project was focusing on reducing budget and saving time during installation. By taking the power aid system as an external package to those existing bikes which need a speed improvement, this would reduce this hassle as much as possible. The solution could be a simple system including a portable power resource, lightweight motor with a wide range of current acceptance, a controlling device and a gear chain drive. Further analysis to ensure safety and pursue manufacturability will be discussed and accomplished in this proposal. For example, the act of matchmaking the circuit without causing dangerous dysfunction and the solution of finding clever installation patterns for almost every ordinary user without a machinist knowledge or sophisticated tools in hand. Therefore, by combining these elements and testifying the suitability of the majority of bicycle designs in the market, this project would become a very competitive product because of reducing production cost from $200 to $70, 30 minutes saved of installation and 40% pedaling energy enhanced at least in 5 miles
