Hi guys
Well I've managed to fit the conversion kit to my Giant CRS3 hybrid. Some observations in case anyone else decides to fit it to this kind of bike.
-The forks needed some working so that the motor had enough clearance (a little bit of filing on the righthand fork)
-The carrier fitted perfectly - no shortage of lugs on the frame.
-Fitting the switched brake levers that came with the kit was a bit problematic – I have EZ Fire EF50 combined brake and gear levers so I couldn't just take one off and slot in the new one So I decided to try to mod the righthand EZ Fire unit by taking a hacksaw to the brake lever-there wasn't any obvious way of removing the brake lever! It worked fine and I now on the righthand handlebar I have the gear levers, followed by the new brake lever and then the throttle. I've left the other gear shifter alone.
-I wanted to fit the pedelec sensor but I couldn't – the bottom bracket and spindle just wouldn't take it.
I went for a 23 mile spin yesterday in the heavy winds we had here in Ireland. I took a hilly route which I normally only take when I'm fairly fit on the bike (not too often these days ). I know now that the battery wasn't fully charged as the red light on the charger hadn't turned green – I only realised that this morning when I left the battery charging overnight.
Overall I was very pleased. It took me a while to get comfortable with the throttle control and it was a big temptation to use it all the time. In the end I used the throttle to get up the hills and on the flat when my speed dropped off. My average speed was 15.6mph which given the strong wind and hills was, to my mind, very good. I also found that I got some decent exercise as well.
I have a couple things that I could do with some advice on
1. When I rotate the front wheel I get the same resistance whether I turn it forward or backward – I expected to get no noticeable resistance when turned backwards. Is this normal?
On the road its hard to tell what kind of freewheeling I'm getting as the tyre that came with the kit is more resistant than the one I had fitted and of course the bike weighs alot more.
2. I would like to fit a pedelec sensor – is it possible to fit a different sensor that might fit the tight space I have around the bottom bracket?
Any help would be appreciated.

Update
Again in case anyone searches for a thread about the sunlova kit. I don't recommend fitting the wuxing cut-off brake levers that came with the kit. The levers are not designed for v-brakes and bottom out against the handlebar in the rain. I managed to get a replacement EZ50 changers with v-brake levers and now I have very good brakes again
The compromise is to cut the throttle grip to a third of its original length as per flecc's mod (see twistgrip) . Now its easy to let go of the throttle while braking. Its much more comfortable to use and its possible to fit bar ends
