Electric Assist E-Bike System Blog Overview
Bike Friday Offers Electric Assist(E-Bike)
Still Focused on Enhancing Your Cycling Experience
We want to help our customers understand what an E-Bike is and why we chose to go with Assist over most E-“bikes” on the market(which really are only considered a bike due to the fact that it could be pedaled but seem to be less and less). We believe e-assist is meant to help you feel powerful and capable of riding your bike. Assisting you when the hill is steep, your load is heavy or your partner is faster. It will keep you pedaling through the variations in your life that might otherwise take you off the bike. A win-win with an E-Bike under you.
We chose the best electric assist kits for cyclists with these values:
- We believe that pedaling is an essential part of cycling. Being able to control your speed/power with your own legs comes naturally to a cyclist.
- A great bike that fits is an essential part of cycling. So each kit can be added or subtracted from your personal bike whenever you wish. It does not detract from your bike, it only adds value.
- It must be able to complete serious adventures. So each kit is built to use over long distances.
- We want our products to deliver the best value when considering weight, function, and cost. A high-quality investment.
Each of the 3 electric assist kits:
- Are 36 Volt Systems
- The Controllers Maximum Amp hours is 15 Amps
- The wattage varies by battery and usage but ranges 288Watts – 500 Watts
- 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 at a maximum speed of 20mph.

Electric Pedal Assist Systems
Rear Hub Drive(our most popular system for NWT and Diamond Llama)
Motor replaces rear hub in the rear wheel. This is a Bafang motor which has been tuned to perfectly work with our wheel size and bikes. It’s the quietest system you can buy and is super smooth which you will love.
– This kit is compatible with all Bike Friday models –
This is another internationally popular system that we are introducing on our bikes! We believe it will be equally popular with our customers because of the unique features it offers. This system packs easily and pairs well without Ligo batteries making it an ideal setup for travelers!
- Is similar to the front hub motor kit but also has an 8,9,10 spd cassette driver. This allows it to work with all rear dérailleurs.

Tandem with a Mid-Drive System
We also make an E-Assist tandem bike. It’s actually incredibly nice to ride and it’s like adding a third set of legs and a dream if only for climbing the hills.
