BionX is the unqualified industry leader for electric bike kits, and they have been for years. Over 250,000 BionX bike kits are being used worldwide, so they are tried and tested on many different kinds of bikes. Now for the first time, you can buy a new PUBLIC mixte or diamond frame bike with a BionX electric kit pre-installed. Get the best of our signature PUBLIC style plus the latest electric technology in one fun, easy ride.


We’ve been test riding BionX on our PUBLIC bikes all around San Francisco and we are confident they can super charge your new or current PUBLIC bike to give you that extra power up hills or when you’re simply tired of riding against the wind or when you need to speed home to get out of the rain or cold.

Take One Home Tonight – Borrow an E-Bike for the Evening

You’ve got to ride these to fully appreciate them. If you’re in the Bay Area, stop by our San Francsico store and take one out for a spin. If you contact us ahead of time, we will be able to loan you an electric bike to use overnight or for the day with a credit card deposit. Find out more about our E-Bike Loaner Program



Already own a PUBLIC M7i or PUBLIC D8i?


We can retrofit a new or used PUBLIC M7i or PUBLIC D8i with a BionX electric bike kit.  This way you get the looks and styling of a classic, highest quality PUBLIC chromoly steel frame with the benefits of new technology.


There are several BionX electric bike kits available, but we’ve concluded that the BionX PL 350 HT RR M battery is the best option for PUBLIC customers based on price, performance and value. We recommend this specific electric bike kit because it provides the right amount of range and power – and they integrate well with our existing PUBLIC bikes with a rear rack mount. Feel free to review our Frequently Asked Questions section to learn more about BionX.

BionX E-Bike Kit from PUBLIC Bikes

We will install the complete BionX rear wheel, controller, throttle, and silver rear rack on your PUBLIC bike. The price of the BionX kit also includes the cost of installation labor and additional parts to convert your new PUBLIC M7i or PUBLIC D8i, plus a PUBLIC Double Kickstand


If you live in the Bay Area, take your bike to our San Francisco store or Oakland store and our sales staff will help you. When you bring your current PUBLIC M7i or PUBLIC D8i to our stores, we will evaluate the bike's condition to determine if there is a need to apply an additional installation charge.


If you live outside the Bay Area and already own a PUBLIC M8i or PUBLIC D8i, you can purchase a BionX kit from PUBLIC but you are responsible for taking the kit and additional parts to a reputable local bike shop to install the system on your bike. The additional parts will allow a local bike shop to convert your PUBLIC M8i or D8i to a 7-speed derailleur gearing system as internal hubs are not compatible with the BionX kit.
