Electric Assist E-Bike System Overview for City Commuters
Bike Friday Offers Electric Assist (E-Bike) Upgrades to make daily transportation easier and more enjoyable
We believe e-assist is meant to help you feel powerful and capable of riding your bike. Helping to assist you when the hill is steep, your load is heavy or the kids had an extra snack that day. It will keep you pedaling through the variations in your life that might otherwise take you off the bike. A win-win with an assist E-Bike along for the ride.
We designed electric assist bikes for city cyclists with these values:
- We believe that pedaling is an essential part of cycling and keeping control of the bike.
- Each kit can be added or subtracted from your bike whenever you wish. It does not detract from your bike, it only adds value.
- It must be able to complete serious life tasks and built for everyday use.
- We want our products to deliver the best value when considering weight, function, and cost. A high-quality investment, often used by generations.
Each of the Electric Assist Systems:
- Are 36 Volt Systems
- The Controllers maximum Amp draw is 15 Amps, capping the motor at 500W maximum
- All systems are Pedal Assist only so there is no electric assist without pedaling (this is key in some laws)
- The Controller can be programmed for your local laws
- From the Factory, we program the motor to support a maximum speed of 20mph.
Overview of the Full E-Bike Friday Suite
Electric Pedal Assist Systems
Specially designed motor replaces cranks and bottom bracket and tuned for the Bike Friday wheel size. This is the PERFECT go everywhere, do everything family mini-van replacement.
Mid-drive Electric Assist is standard on the Ever-E-Day e-bike
– Available on non-folding Bike Fridays: Ever-E-Day, Haul-a-Day, Family Tandem, and OSATA –
This is a very popular system in Europe where millions of electric-assist bikes are sold yearly. It is little known in North America and we have been thrilled to discover it. Many of us on the Bike Friday team have put this kit on our Haul-a-Days and love it! The Mid-Drive is the perfect set-up for the challenges of parenthood because the loads never get lighter as the kids keep growing and the loads that come with having them don’t get any smaller.
Marry this system with either of our cargo bikes, the Ever-E-Day and Haul-a-Day, and you have the perfect family vehicle.

Here is what a Bike Friday customer had to say when she added an electric assist to her Bike Friday:
First off, just wanted to let you know how much I’m enjoying my upgraded Bike Friday. It’s actually making me cycle more, and work harder, and sweat more. I spend more time in the saddle and more time spinning because the psychological hurdle of wondering if I’ll conk before I make it all the way back home is gone. Also, I’m freed to explore the hilly areas around me that I was nervous to do much of before a bit of power. Because I have a built-in habit of going for a certain amount of pedal resistance when I ride, my worry that I’d just become lazy with an e-assist is fading. I now get how this technology can be great for true cyclists….” -Abby
