Build it yourself

After a lot of research i converted a couple of my bikes to electric assist. In my view the best components and latest technology come from ebikes.ca in canada.

https://www.ebikes.ca/

Take a look at their cycleanalyst and phaserunner setup. They are brilliant open source products.

Is the place to go unless you are going to try to build your own. Great service from a uk run company with all the advantages of trading with China.

I did one of the Ebikes brompton conversions and turned my old specialized tri cross into a long distance commuter with a 2kw rear hub motor and 56v triangle battery. The performance is stunning and fully programmable. I get around 100 miles per charge at reasonably mad speeds, much further if one can remain sensible.

Conversion costs range from £500-£1000 plus battery. You remain in charge (!) of the setup with no hacking to be done and no reliance on big manufacturers for batteries and parts.

Look at the advice from Justin regarding hub vs mid drives. Bike manufacturers go for mid drives because that suits thier current format and with the low EU limits gearing is more important. They have their place on mountain bikes but for fast road/commuting I would seriously consider a hub for a reliable, silent easy build.
