Have an old bike in the garage that is taking up space? Let us convert it to an electric bike and get twice the bike at half the cost. Guaranteed!


Hello, I am Dr. Carpenter, the CEO of Island City Bikes, LLC. In 2017 we began selling Bafang motors and components. Soon after, we began to buy bicycles in bulk and began to convert them into electric bicycles. However, more and more people began to bring us their bikes and ask if we could covert them to electric. Today, converting existing bikes to electric represents 80% of our business. In the last 12 months we have converted over 380 standard bikes to electric. Some of our clients ship their bikes to us from all over the US for conversion. We now have a drop off and pick up location serving the Sacramento Region. Give our office a call for more information.

Three reasons why you should consider converting your bike to electric rather than buying new.

Cost: The cost to convert your current bike to electric is about 1/3 what you would pay for a pre-built electric bike. In addition, we exclusively use the Bafang 750 watt or 1000 watt mid drive motor. The cost of converting your bike to electric with a Bafang 750 watt motor and 48v 13Ah battery is only $1,400. The average cost of an electric bike from a bike shop with a 500 watt motor and a 13v 10Ah is well over $3000. We only use the Bafang Mid Drive system, the most popular motor in the world.

Size and Fit: One of the common complaints about eBikes purchased in stores or online, is they do not fit. Nearly all eBike companies have adopted the “One size fits all” model. Other companies might have two sizes at best. The result is that many people end up with expensive eBikes that do not fit. 

Recycle: When you re-purpose your existing bike by converting it into an electric bike you extend the value of your original purchase and…you keep one more item from ending up in the landfill. Your bike, converted to an electric bike, will provide you years of service.

Price to convert your bike into an electric bike: 

Conversion with the BBS02 750watt motor and a 48v 13Ah battery; $1,400.

Conversion with the BBSHD 1000 watt motor and a 48v 17.5Ah battery; $1,900

(Please Note: The 48v 17.5 battery has Samsung 35E Long Distance Cells and is required for the 1000 watt motor).

Included in our conversion service:

*** Bafang BBS02 750 watt or BBSHD 1000 watt motor

*** 48v or 52v eBike battery. We do not use 36 volt systems.

*** Cleaning of the bike: The bike will go through 3 stages of cleaning. See our FAQ page on why we spend so much time on cleaning a bike

We Convert Cargo Bikes into Electric Bikes


Cargo bikes are one of our specialities. We convert Xtracycle, Yuba Bikes, Surly, and many other cargo bike brands into eBikes nearly every week. The picture above is of a Xtracycle we converted into an electric bike using a Bafang BBS02 750 watt motor. Cargo bikes are increasingly growing in popularity and many find adding a motor to the cargo bikes allows it have the power necessary to climb hills and ride against the wind. We carefully convert each cargo bike as if they were being made to carry our own children.

We have converted so many cargo bikes this year we decided to have a special page showing the converted cargo bikes.


In the beginning we did not plan on specializing in transforming cargo bikes into electric bikes but soon word got out that we were providing this service and now we have at least one, if not two, cargo bikes on the floor of our shop each week. They are heavy, take up a lot of space, but we have done so many of them we can get the job finished and back to their owners pretty quick.  

Meet Leonard


This Leonard, one of our favorite clients. He stopped into our shop today to look around, cause general havoc in puppy like fashion, and then decided he loved to sun in our window. Leonard is a 4 month old Golden Retriever and already very well trained as evidenced by the fact he only peeped one on our floor! Thanks for the visit Leonard and sorry we did not have a bike in your size.
