Derbi senda with hacker motor

Postby bionicon » Fri Jun 09, 2017 2:41 pm

Hello everybody I want to share my latest project. Its not finisched yet but i have already 9 hours of drive-fun:) :D
Its made out a derbi senda with alu-frame adjusted to adapt the new motor and batterybox. The motor is the hacker Q150 -45 with 71 rpm/volt, a 14s lippo battery with 5kwh capacity. It works with the the hacker hst350 controller ,totall weight is about 85kg.
Till now its the most fast electric bike i ever did drive it hauls like crazy and cannot give full trottle yet(some settings must be adjusted.) Before i played with the idea to put that motor on a bicycle, but now it scares me :lol: I will make a short video soon, here some pics of the building:

Cool to see the build process. As I said before. Fantastic build. I think you have a very special motor and controller combo. Insane power yet light as a feather.

Look forward to see videos.

Looks fun. You might want to monitor for heat from eddy currents where the rotating motor magnets are close to the frame.

Great conversion^^
the "motor box" is a good idea to give that motor protection against dirt and water.
does the rotor show magnetism on the outside? if no, than there should not be a problem with additional losses as mentioned before.

there is almost nothing available about the haker stuff in the internet and you are the only person in ES i know who runs such drive system. please keep us updated.

thx everybody for the nice comments, gonna try to make a short video next weekend. Just finished a long weekend at the sea with the bike :D I did ride it everyday and the longest trip was arround 120km long(cell voltage was then 3.7 volt so not empty yet) this at a average speed of 40km/h.Top speed is arround 85km/h.
It has not the wheely -torque at take-of but accelerate fast, I will try to capture that with a video :lol:

Video. Nice. Your build is so clean and uncluttered. Really nice craftsmanship. And that color just makes it all look even better. Seems factory build.
