Adding Brushless Front Hub Motor Feedback

I have a specialized hybrid road bike that I would like to add an electric front hub motor to. I would like to go around 20mph, and I would like a 10 mile range (distance to and from work).

I have my eyes on this kit;

36V 800W Brushless Hub Motor Front Wheel ($255)

http://cgi.ebay.com/ws/eBayISAPI.dll...MakeTrack=true

And this battery;

Li-ion Battery 36V 16AH with Aluminium Case BMS and Charger ($469)

http://www.ebay.com/itm/Li-ion-Batte...item35c5f30260


This seems like the most bang for your buck as far as adding a front hub motor to a bike, what do you guys think? Buying a pre-make kit of this power would cost twice as much, and I am always ready for another DIY project.

Any input is appreciated, I am in the research phase still. Any links to articles of how to put this all together would be supper useful as well.

Thanks!

I bought a Crystalyte front wheel kit about 6 years ago, and I had got a set of SLA batteries
at that time as well.
I converted a Sears mountain bike, it has a steel front fork, so the motor works well
in the front. I put the batteries on a rack on the back, so the bike seems balanced out well.
I have the batteries in a Crystalyte battery holder with a key switch. I then put a saddle bag
setup over the battery holder, which hides it very well. The bike rides well, with pedalling and
the front motor pulling, like driving and all wheel drive vehicle!

This past winter, I bought a rear axle kit, and converted the bike to a 3 wheel tricycle to
navigate the ice and snow, without worrying about slipping and falling. So again with
pedalling driving the rear wheels, and the front pulling, it is very stable on ice, and it goes
well when going out on the bike trail here before it gets the snow cleaned off.

Then this spring, I converted back to the normal 2 wheel setup.

So for me, the brushless front motor set up have worked well, and doing them both DIY,
doubles the enjoyment.

As far as info on putting it all together, there was a company in Calgary that used to have a utube
video, but its not on their website any more. You might search utube for it.
You might also find information at another website I like at:

Since I built my setup, there has been a lot of front fork re-enforcement add-on's for aluminum
front forks, so a front fork set up is viable for aluminum forks.

Happy hunting!!!

I asked a question a while back about front vs. rear as I get ready to build my bike / motor system. After lots of research I have decided to go with a Speedhub by Rohloff at http://www.rohloff.de/en/products/speedhub This only leaves me the front tire for the motor so I'm glad to hear that with motor pull and pedaling it is a nice balance.

Thanks
