Building an Electric Bicycle - The Cheapest Form of Hybrid
Many blogs and sites on the net talk about gasoline-electric hybrid model vehicles. However, there is a cheaper hybrid version that you can use: a human electric hybrid bicycle.
A well constructed hybrid electric bike functions in a very similar way to a simple electric hybrid car. The assembly is arranged to permit the electric motor to assist with acceleration, hill climbs, and with general movement. Just as gasoline is the primary power source in the simplest of hybrids, in the simplest forms of electric bicycle, the primary form of power is still supplied by the rider, and in both cases, batteries provide an assist which permits the vehicle to go longer and faster with less effort.
Peddling on the part of the rider can be used both to move the bicycle and to recharge the batteries. Regenerative braking is also an option, providing another source of power for the bike batteries and making for much easier riding in hilly riding areas. In hybrid bikes, one of the most complicated parts of the system is connecting the electric motor to the wheel, so that power can be used to push the bike, or stored to power the bike at a later time (by using the system in reverse). While there are many ways to do this, one of the easiest is via a simple roller which can be brought to push on the tire when needed.
As the components of an electric bike (with the exception of the batteries) can often be obtained from salvage or scrap, the price of an electric bike can vary widely. However, I recommend caution with parts related to braking. Personally, I would always buy those parts new as I always want to be sure my bike can stop!
As with any hybrid vehicle, the weight of the hybrid assembly should always be considered at all times in your conversion process. The last thing you want to do is create a bike that’s impossible to peddle without the batteries on.
Kits and advice on creating hybrid bicycles are available across the Web as well as many businesses that sell completed hybrid conversions.
