- they were just the widest plainest looking things from a local big chain bike shop. Possibly BBB brand
- hot glue and cable ties was definitely how I attached the front one
- the back one I vaguely remember using the actual metal bracket that come with the guards,
- the front clip part was chopped of, as during suspension travel it just unclipped itself anyway.
- BTW the front one still allows water front the road to get flung forward, then blown back in your face when riding in the rain.
Here are some pics that might help: (from this post
- On the right I had front brake, trigger shifters for the rear, and three speed switch.
- On the left I had half twist throttle, regen brake levers, and front shifter.
- This was to avoid having my right hand doing all the important stuff. Throttle, Front brake, and rear shifter
- Also I never got around to mounting a proper rear brake, and relied regen for the rear. Fine for commuting style riding, but not great for off-road.
83.6V hot off the chargers, but settles to ~78V once the surface charge is gone from the LiFePo4's
~55-60kph on the flat.
I think I ended up dialling down the amps a bit for my commute. I also had a 3 speed switch, that allowed me tame things down. Which was definitely a good thing for a bike that quick. I think I had it set to be about 30 kph on 1, 40 kph on 2, and all out on 3. I would always switch it to 1 or 2 when letting someone ride it for the first time.
Hope that helps.
Since it looks like your are building your first ebike I might add a few comments regarding fast ebikes.
50kph + is way fast on a bike. You will need good brakes. I used Avid BB7s which are very good.
If your roads are rough, dual suspension will be on your shopping list. As soon as I started going over 40kph I started searching for a dual suspension frame to use.
At 50kph+ you start running out of gears, and can't pedal quick enough. I ended up getting a 52T chain ring, so I could keep pedalling. Well worth the money.
At 50kph you end up using a lot more power to get from A to B. So you will need a bigger battery. For my 15km commute I shaved ~5 mins off the travel time going from 40kph to 50+ kph bike, but ended up using twice as much watt-hours for the same distance. Halving my useable range.
Going this quick made me worry less about cars behind me, but made me worry a lot more about those in front of me. Cars don't expect a bike to be going that quick, so you need to be very alert for cars coming out of side roads etc.
I now ride ebikes that average closer to 40kph on the flat. I personally find this the best compromise between risk, efficiency, range and fun.
