I am in the process today of fitting DaaHub to a Whyte 28" Hi bred (when I get a moment)! Not finished yet but this will give an idea of the look.
That looks really great. What RPM/wheel sizes will this motor be available for? What is its design voltage? Does it use a Hall sensor?

Thanks Clv!

Will be available in 20, 24, 26 and 28 / 700c wheels… Disc or v brake options.

Rated rpm is around 280. Design voltage 36V

No, we don't use hal sensors, as they are always the first component to fail in a motor. Without hal sensors, the internals of our motor can reach over 160 deg C without failure…

We have been working with a Japanese motor company for over 2 years to develop what we believe is the most stable and reliable hall-less controller available.

All the best

Great replies so far!

It seems that there are a handful of common ideas;

  • Do you like DIY - the fulfilment of making an e-bike your own, despite the hassles?
  • Is your bike fit for purpose - some kind of litmus test to see if adding a kit would really work for your bike
  • Are you trying to save money - compare with the costs of a completed e-bike
  • Trusted suppliers list - a directory where you can get lots of electric bike parts

I was wondering, for the folks who really do want to convert their bike, whether some sort of 'Bike Conversion DVD course' with printed notes and a suppliers directory would be useful? As I said at the beginning, some 12,000 people are searching for conversion kits on Google each month (and that's growing) so its not as if there's no demand.

Maybe someone technical would be interested in partnering with me, and splitting the booty? What do you reckon?

A DVD and/or manual sounds like a great idea, and a potential business opportunity! Perhaps the forum could produce it in collaboration with it's more knowledgeable and experienced members ;-)

One thing about conversion kits....unless you buy an expensive kit from one of the big brands, the instructions that come with the kits can often be a bit difficult sometimes (assuming they're even in English!) and then if you're using batteries and bits from different suppliers, there's other things to consider. Then there's all the tip bits of information, established ways of doing things etc members have learned. All of this could save people a lot of time and make the job of converting a bike easier and more enjoyable.

In my own experience of fitting a kit last week, I had a hard time figuring out the pedal sensor assembly as the instructions for my kit were not in English. I searched everywhere but couldn't find any generic instructions online. It was only the support of other members that helped me figure out how simple it was and where I was going wrong, ditto for fitting torque washers and figuring out whether I needed torque arms on the drop-outs.

Can I install an eletric motor kit in a Trek 750 with 700 wheel?.

Yes to all. In fact 600w will be quite powerful.
