The Enigma of Electric Assist #2
The Enigma of Electric Assist
By Alan Scholz, Co-founder/Designer of Bike Friday & Burley Design
The main mystery of Electric Assist for bicycles. Why is it not more popular in the US?
It is wildly popular other places. What do they know that we don’t? It seems like it should have so much going for it. It is a tremendous and super economical solution for a lot of folks. And did I mention fun? More than 32 million of them were sold in the Asian Pacific countries alone last year. More than 23 million just in China. (200 million in use in China!) The Europeans put another 1 & a half million into use last year.
In North America? A rounding error amount of around 150 thousand! That is less than 1 in about 6000 people!! Compare that to the over 7 million cars sold in the US in 2016. (That’s 2 out of every 100 people bought a car.)
My experience these last 3 years has motivated me to find out why such a fun, healthy, inexpensive, uplifting and effective transportation is not catching on in a big way here.
Before my epiphany. ( I didn’t get it)
I have watched bicycle assist systems be innovated since the 1970s. Back then they were little wheel drive gasoline motors. Noisy, dirty and to me, as a cyclist, not at all attractive. They did not do well and it is easy for us cyclists to see why. A couple of years ago customers started talking to me about their interest in electric assist. I have been watching the development of dc motors & battery systems for bicycles for about 20 years now. The ones I had seen or tried were still lacking, to my sense of matching a bicycle’s quiet elegance and filling needs that I understood. (I think I might have been a strong cyclist snob too!)
But then 5 years ago I started designing a cargo bike system optimized for women and families to complement and improve on my many years of kid trailer design work. (I invented the Burley Bike Trailers for my own kids. I should have understood the need for the assist!) Near the same time several customers finally were able to make me understand that there were all these other potential values in having an electric boost.
One ride changed everything. (The light goes on)
And then I rode one that was quiet and smooth and made my heavy cargo ride like I was super fit! On the lowest setting it stilled seemed like it was all me on a good day and on a lighter bike. On the second setting I felt like I was having one of those great days. On the next setting my ride to anywhere was quite predictable as my higher capable speed made it clear that I could reach wherever I was going without over-working. The high setting was enough to ride even if I was not feeling motivated because it did more than enough to cover my reticence. I found I do not ride less or at a lower effort. If anything, I ride more and exercise harder because I feel better! I still go on bike rides with the club and tours without the assist. But on a daily basis I use the assist to have predictable transportation. Sometimes with quite a load. If I was riding with others that were faster I would definitely want the assist to add the extra bit to keep up with them. That is not cheating. (Mechanical doping, yes!)
Why aren’t others in North America taking to this in millions?
The challenge I have found is that the field of electric assist is darn confusing! In 2013 I started my education. What I learned was the electric assist was quite a viable addition to lots of our individual needs and also could give a great experience. I found this as a really pleasant surprise to me. Many folks in North America are in a similar place to me about electric assist. Interested, to very interested, but not sure of the best way to proceed for a positive result in both the cost and the experience. And with those low, low sales numbers it means most of us have not even had a test ride. And even with test rides, I know they are not all alike or all good. So here is my venture into become capable of understanding this wide, exhilarating confusion of electric assist innovation going on. I hope it will help you understand how it could make you feel more powerful and be part of the climate change solution while making the concept of home economy significantly better.
Don’t call it Doping!
You may have heard about European professional cyclists in the last year or so showing up in the news “mechanical doping” in pro races. Maybe even for years since 1998! That my friends means the electric assist has come of age when it can be stealthed into the echelon. Wow! We need to get some of this for ourselves. I know I want some. Small, quiet, light. This is not drugs or cheating for us. For the pros yes. For us, it is an enhancement that will give you better exercise, a smaller footprint, and a new perspective. I would like to show you why.

What is the intended scope for our research into the enigma of electric assist?
A. Main reason for this project is for making a rather complex thing simpler, to make the experience more predictable, and to make it cheaper for all by sharing so as to not require the individual to try by hit or miss. A big piece for me is sharing a huge potential I found that I did not expect or value. As I was dispelling the enigma for myself, I got schooled! I used to say it was useful for the right person and the right situation. Kind of smug of me as it turned out. I believe now it could be useful for most people in different situations most people have in their lives. Somebody should do something to make it less mysterious! Here we go! (Green Gear R&D)
1. We are testing the components that make electric assist systems, We are doing that by having many people here at the shop use them so that we can have their candid comments on their use.
2. The testing will be interspersed with my comments based on the subjects I listed above. Some are quite surprising, some are really hidden gems that for the right folks will make their life a bunch better, and some are great gossip topics that I think we will all enjoy. That Little wheels Fly will not be your only secret!
3. I am eliciting stories from Bike Friday Community members with electric assist experience. Please share with us all and help us forward in this research. Please do send in your experiences electrifying your bikes as we would all love to hear them. Some that were shared with me finally convinced me to look into this enigma. And I am so glad they did. There is a huge amount of value to it. My first ride on a good one was eye opening. My first 2 or 3 electric bike tests, not so good, the next was wow!
4. My goal will be to make an easy way to choose what is right for your situation & to have a great experience with your first assist set up.( I didn’t get one to work for me until the third try! Time, money, and frustration.) I want to make also predictable useful kits available for the community that will work well for the different Bike Friday models.
B. What will we test? Here is the main list. The technical side yes but much more will be our human experience of it.
1. Motors – We will be testing total of about 15 motor systems. We have already done 6 that are in use or rejected. It is very clear not one best system or best way. We will be doing at least 6 front hub motors, 3 mid motors, and 5 rear hub motors.
2. Batteries – We are testing 24 volt, 36 volt, 48 volt, and 52 volt systems. Small and large capacity ones. Yes confusing. These include the newest most advanced Lithium batteries. (most contain the same cells that drive Tesla cars.) We will include a world first, a travel legal battery by air for electric bikes! Just came out. We have videos now showing travel with it on our new super light compact “The pakiT.” Plus all the best practices for charging, expectations for longevity, and real time experience caring for a high capacity light weight battery.
3. We will be testing systems with different power assist levels. With our emphasis on legal limits and speeds. 250, 350, 500 watt systems, & the legal limit in the US 750 watts. ( a full horsepower! Who is helping who?) We will talk about human power and flying the English channel with a 300 watt human. This subject is a huge part of the confusion about electric assist. There seems to be a fair number of hot rodders in the US that are not cyclists as we view it. Do you really need a 3000 watt system? (4 horsepower! You could fly with that) I make the case that they are not electric assisted. Also we will cover an over-view of laws covering ebikes. Links to good resources we find too.
4. We will be comparing hill climbing ability, speed, and range. Here you will see the huge difference between a pedal assist and an electric assist. Yes weight really does still mater and a light bike that fits goes further and faster. Just like it does with our 100 to 300 watts of personal bike power. Will also have a discussion on regenerative braking. A pleasant and surprising win for tandems especially.
5. We will compare system weights and how ‘bike like’ the systems is and how easy to ride when the assist is not being used.
6. We will try the different control methods. There are at least 5 or 6 different power control methods and I already think this is one you must know about before you get your assist. It was the most confusing for me and it has the most difference in making the assist recede into the background while you and your cycling skills lead. Also large cost differences and system complication.
7. We will use several different instrumentations from very simple to ones that require some skill to integrate into your cycling skills.
8. We will always be looking at the systems for optimization of use for different needs and uses. Plus we will look for optimization for simplicity of use, maintenance, and cost.
9. What systems do we think is best for each of the Bike Friday models. Produce a buying guide with the project results.
