A couple of months ago I asked the forum for some advice on an e-bike setup, mostly due to the fact that I have very limited electronics knowledge (notwithstanding 15 years in the automotive industry working as a mechanic and master technician) I had spend many evenings searching through the ES forum but all the talk of 2806, mosfets and shunting seemed a little overwhelming for me - especially as I am the kind of person who prefers to know the why as well as the how.
But, just as many of my automotive clients had relied on my own experience and knowledge when it came to modifying their car, I ended up talking to Hyena. After test riding one of his creations and discussing my project in depth, I was convinced that Jay knew his stuff, was honest, down to earth and trustworthy - ordering his 72v Hadron kit shortly after.
The bike prior to ebike-afication - used for a combination of onroad/offroad/commuting/thrashing etc
After a short but unavoidable delay due to OS parts deliveries, I headed over to the Hyena's place last weekend and after a bench test demo on the kit setup and operation I raced home and spent the rest of the day installing the kit onto my Trek 4900 hardtail.... which is now an absolute f%@king weapon. Jay has de-tuned the kit slightly as I did not want a vented hub motor (for rainy, muddy and dusty riding) but still this bike is dangerous in the wrong hands!!!
Launch is quite controllable due to the tyre/wheel size and my weight - acelleration is fast and linear up to 60kph but if I take off with hard pedalling I am hitting 60 in about 4 to 5 seconds. Top speeds so far is 76kph on a dead flat road and 87kph on a mild downhill, but the sweet spot is found when you snap the throtle open at around 30kph.
The battery is supported by a marine plywood base, coach bolted into a steel bracket - generous lashings of gaffer tape ensure everything stays where it is suposed to. The controller lives underneath and the whole unit will be encapsulated in a fibreglass faring shortly - with ducting to keep the controller cool
I upgraded the crappy single piston Hayes Sole brakes to twin piston Avid Elixirs recently (185 front & 160 rear) and thank god I did - stopping a 36kg bike and 120kg rider from almost 90kph is a pretty mean feat - I dont know how you guys with v-brakes are still alive!!! The rear caliper still has heaps of clearance to the motor but the GM spin-on adapter places the rotor way to close... will have to get one made that places the rotor another 15mm out
After trying to fit 3 switches, twist throttle, CycleAnalyst, lights, 2 brake levers and 2 shifters and a bell all onto the one handlebar, frustration and impatience took over so I ditched the bell and put some old bike parts to use and build this dual-bar setup. Like it or hate it, this setup works perfectly and everything has a place - I just hope I never go endo whilst holding onto the lower grips ~SNAP~
So from here on it, my priorities are to get the rear brake happening, lose as much of the gaffer tape as possible and make the fibreglass faring - then strips it all down and paint it.
Massive credit to Hyena for his know-how and connections + a big thanks to everyone who has ever posted something useful on the ES forums

but that's alot of momentum you're carrying and 87km/hr is nuts! Take it easy mate!
they are now about 100mm each side and look like those dumb arse fixed wheel courier bike handlebars - they hold the CycleAnalyst and the Nitelight now and thats all!!!
