Neodrive 250W electric-assist system on HP Gekko FX26

We have just finished putting together an HP Velotechnik Gekko FX26 folding trike outfitted with a Neodrive 250W electric-assist system.

This is a very nice system and hard to find. The first test drive in front of the shop was on level ground, but the system seemed quite powerful.

If you want electric assist, but still want to get exercise, the Neodrive is a good choice. It features a strain gauge that detects when you are pedalling and then magnifies your effort.

If you don't pedal, it doesn't either. If you do pedal, you feel like a bionic person.

This system has taken almost a year to get together. We have procured the drives and the batteries. We have also sourced locking brake levers with built-in cutoff-switches. We have also designed a new mounting system.

We've set up two systems on ICE trikes and one on a Catrike to work out the kinks.

Technical notes:

For anyone looking closely at the pictures, you will note that the battery is mounted on the left side and this will cause difficulties when trying to fold this particular trike. Our battery mounting brackets work on either side, but, the electric harness is not long enough to connect to this particular battery when mounted on the right side. As soon as we get an extension or a different harness, we'll move it to the other side.

The price of this trike and assist combination is less than $5000, and this includes a very high-capacity battery.

We'll be doing some testing with this system and posting a more detailed review.
