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.

United Kingdom 

Just been having a look at this thread. They are an interesting concept.

However, the law does apply and there is a wattage max and speed max allowable to be lawful.

The info is available online, I know because I was taking a look the other day.

Above that, it’s classified as a motorised vehicle.
Then requiring insurance, Tax, MOT etc etc.

If caught without, it could risk your actual driving licence.
The same laws apply as Go-Peds Petrol / gas and electric. And genetics electric scooters.

How anyone would get such a vehicle legal I don’t know with out great issues and problems associated with testing.

Under the speed and wattage threshold is completely FOC no problems.

There are many on eBay though and other online sales that are way over the legal specs.
It’s easy to say who will know, but anything is possible and as I said you could end up with points on your Car / Bike licence or what ever you hold.

There is a safety aspect too, it’s a difficult one.
Fairly high torque, but low speed isn’t bad though for hills etc. 🇬🇧 Made In GB. 🇬🇧

It May Not Be Very Fast, Never Has Slow Looked More Bad As*.

My electric bike is “switchable”

Ie it can be used up to the legal limit of 15mph on a road...
And if I choose I can switch on the electric assistance to go beyond the 15mph off road.

I have to say it suits me perfectly.
There is /was nothing worse than touring at 15-20 mph with the motor kicking in and out. It becomes a real chore.
My bike feels perfect now... much more useable.

I’ve zipped about on a few with import motors, and it’s surprising what the difference gives. If you’ve got the legs you can mash a road bike (non electric) up to 30mph, so really can’t see the issue to some extent if people are considerate of others and spatially aware - that being said, irrespective of what should be considered a legal (sensible) level in anything will always be exceeded by certain folk.

We had a great time in Tampa too using the electric scooters, a really excellent idea and for the part very well adopted. But I can see that it could easily be a nuisance for pedestrians and vehicles all the same. If the expectation of being cut up or jumped at is present then we just ensure we keep aware of it!?

France 2011 Defender 110 Puma 2.4 XS DCPU Zermatt Silver

I have a KTM electric Motorcycle that I use for trail riding. https://www.ktm.com/en/e-ride/freeride-e-xc/Overview

It is great fun, but after 4 or 5 years the ride time is degrading, so I have been looking to replace or upgrade the battery. But a replacement from KTM is over €3000 ! I cannot find anyone else to supply (I also emailed the Chinese company Chopcat listed, above). I am starting to wonder if I should open the battery case and replace the internals myself, but not really sure where to start...
