Convert your existing bike into an electric bike

Island City Bikes, Alameda California. Convert your bicycle into a electric bike

Welcome to Island City Bikes in Alameda, California. We specialize in converting bicycles into electric bikes. I am Al Carpenter the founder of Island City Bikes. Over the years I have had a plethora of experiences but none that is so satisfying as being a part of the eBike movement. Electric bikes are a great way to exercise, explore, go on a journey, and even replace the car as a means of transportation.

Interestingly enough we started out as an online business selling Bafang motors and batteries. Then we began building electric bicycles and selling them locally using the Bafang Mid Drive System. However, more and more people came to us with their bike and would say, "I already have a great bike, I have money invested in it, it is comfortable, and I do not have space for a second bike...can you install the Bafang motor on my existing bike?" Now, we convert more standard bicycles into electric bicycles than anyone in Northern California and it has become the focus of our business.

When we convert a bicycle into an electric bike we do not simply attach a motor and a battery and send you on your way. It is a long, exacting process. Visit our conversion page to see all that we do. It is not our goal to make a fast or powerful electric is to make a safe electric bike. Yes, we can build a bike that can reach speeds in excess of 70mph but we would only do so under strict guidelines and only for professional riders. We build good electric bikes that are safe electric bikes. That is the standard from which we will not deviate. 

We provide both service and sales.

First: We convert standard bikes into an electric bikes using the Bafang 750 or 1000 watt mid drive motor.  We have converted just about every type of bike one can imagine. All of our conversion have to go through a very strict safety inspection to determine if it can safely be converted into an eBike. Our inspection means that we thoroughly clean your bike then our mechanics disassemble it in order to clearly ascertain the condition of the bike. We look for hairline fractures, missing parts, broken parts, areas that are intact but need repair, and the condition of the wheels, tires, and brakes. The reason for this inspection is that the Bafang mid drive motor is powerful and will exploit any weakness in the bike. If we discover anything that might make your bike unsafe as an eBike we reassemble it and return to you at no cost.
