Default Project Q bike

I've never been fully satisfied with electric bikes.

I'm not going to put names to the following bikes because all e-bikes fall short of what I think they should be, though the informed might work out which they are.

Take one highly thought of one that's underpowered. On one trip up a very long hill commencing at 1 in 5 (20%) with me working hard at 4 mph, gradually increasing to 6 mph as the hill lessened and ending with me exhausted well over ten minutes later as I finished it's 1.3 miles length, I remember thinking that I'd be no more tired walking up there and keeping the £1200 in my pocket.

Then there's the well known bike that only works properly if the rider helps it! That's a crazy reversal of logic if ever there was one.

Yet another has adequate power to potentially do what we expect from electric bikes, but that potential is squandered by inappropriate parts and sheer lack of cycling qualities, efficiency and essential basics.

And what are we supposed to think about the very expensive bike with drive through gear suitability for hills that has to be pedalled away at first until the motor kicks in? When I come out of the supermarket with 10 kilos in bags that, added to my own and the bike weight, means I have to pedal over 100 kilos, how am I to do that up the steep one way hill outside to get the motor going?

Or the bike, not a "parts bin" job, but one designed from the ground up with the only rear sprocket well out of line with the chainwheel?

With every indication that the industry wouldn't reach the demanding standard I wanted before I was too old to cycle, the only answer was to use my own skills and knowledge, but kits were often no better unless illegal, and I was insistent that I wanted to create a legal bike. Not because I'm prudish about the letter of the law, but to prove that it was possible by good design and build to achieve everything that was needed within UK law.

The result is based on one of my own bikes, but drastically changed, and when you first see the Q bike it will disappoint many, especially if they are fashion concious. But fashion has been the curse of the cycle industry for nearly three decades now, making the majority of bikes the most inefficient that's ever been known in the whole history of the bicycle, a curse that's been carried over into electric bikes.

So don't be a victim of fashion and fooled at first glance, the Q bike is an always legal bike that in road use does everything we'd like but never completely get. It's combination of versatility and capability is better than any other UK legal e-bike in the world. (he modestly said )

N.B. For those owners who've previously asked about photos of the internals of the Quando and Torq motor, they are included in the Q bike article.

To see my motivation for the project, the problems involved, how they were overcome, and the all-round abilities of a truly good electric bike, click here. It's a long read.

There's a 13 page PDF download available at the foot of the home page as well.

Very interesting article Flecc, and it's nice to see you named your creation after me.

Hi Flecc,

I'm positive I could hear you banging about in the shed from Cambrideshire!

That is truly an excellent series of modifications and I'm sure eZee would be very interested to see what you have done.

cheers
Russ.

An excellent job Flecc, very well planned & constructed, you must be rightfully pleased with yourself.

You say your creation is not fashionable, I would disagree, surely if the purpose of fashion is to attract admiring attention then I would say your new bike is very fashionable, at least when going uphill.

Also worthy of congratulations are the well written articles which I've read briefly and already learned from, I will digest them fully in due course.

Ian.

Thanks Quicken, Nigel, Russ and Ian, I'm grateful for your positive comments.

Yes, Ian, I'll certainly admit to being very pleased with the result. I knew that I couldn't fail to get a substantial improvement, but it's always impossible to predict the degree of the cumulative effect of efficiency measures. That's even more than I'd hoped for, my aim being that the bike should handle anything up to 20% for an unfit rider. The fact that it can perform well beyond that is the biggest bonus possible, and the range is the icing on the cake.

I'll confess that to my eyes it is fashionable, but knowing the popularity of the MTB style, I doubted that others would share my view.

One thing that has really surprised is that the efficiency has topped the Giant Lafree Twist series, with 12% higher consumption producing a minimum of 42% more performance. I could never have predicted that outcome.

flecc
as you possibly know some of what you have done is beyond me, ime intelligent enough to learn but its a slow process now, but i still can understand some of your achievements and i congratulate you on all of them.

it has been a thought in the back of my mind for a while now why doesn't this man build his own bike, it must have been obvious to anybody reading your posts and looking at your work that you could improve on the stock item, and you certainly have.

Many thanks Mike and Leonardo.

Yes, please do link to your forum by all means Leonardo. From the final page of the Q Bike article there's a link back to my Torq Talk website where any one of your members can contact me if they have a specific query on something.
