This is my second build, My first was a Giant XTC 29er which I fitted out with a Cyclone 1200w motor kit and LiFePo 16Ahr battery.
Having researched intensively I decided that mid drive would suit what I wanted to do which was off road and bush trail riding.
I've seen a lot of Ebikes online and so many of them just look downright hideous, So I set out to try and put together a bike that is a little more discreet and appealing to the eye while possessing all the qualities of a good full suspension mountain bike.
I learnt a lot from the first bike including what would go better on the next one.
The first thing was to reduce the size of the speed controller so I purchased a Grin Tech Infineon 18 FET 35Amp controller that was nearly half the size of the stock standard Cyclone one.
The second was to run Lipos in a pack as per the EGO Kit, This wasn't a problem as I have 6 12s 5000 MAh Packs for my RC Mikado Logo 600 Helicopter with a charger that can crank out 40 amps all day long. I do currently charge 3 of these packs from 20% to full in about 40 mins flat.
I'm running 3 of these in my pack to get 15AH @ 48 volts weighing in at 3.95 kgs. This weight i hardly notice in my really supportive Camelback pack with a fibreglass Lipo liner.
One of the things I've noticed with off road bike mods is that the motor is always below the frame which to me not only looks awkward but would serve to hook logs etc and take a fair bit of abuse from whatever the front wheel throws up at it. I've utilized the space between the rear shock and down tube in the hope that the whole arrangement also looks a little more discreet.
The motor mounts will be powder coated the same Metallic grey as the Bike frame.
So far I have had a blast on this thing, Top speed is 55 Km/hr - a bit slower than the XTC 29er at 65 Km/Hr but it also climbs like a mountain goat. All up weight ready to go is 19.3 kgs. Everything seems to be holding up and I'm glad I went with the BMX drive chain - It hasn't stretched anywhere as much as the original cheapy chain that came with the kit.
