Changed to an ebike

[Old Git Racing]

Since having a knee replacement last year my legs lost a lot of muscle. I've tried riding my normal bike but its just too much.
Thought long and hard and finally shelled out on a Boardman Hybrid e. Glad I did now, I'm back on the road. 4 levels of assist, none, low, medium and high. The assist comes only when pedalling so you still have to work and its not doing it all for you. Aim is 60m a week for now on middle setting, made that and more this week, longest ride 19m.
Take out the motor and battery and it rides like a normal bike.
I've changed the saddle for something a kinder on the arse and have some Ergon GP4 grips coming, apart from that it is a good quality well made bit of kit.
Will I get back to a normal bike? dunno yet, maybe a combination of both.

Knee care is important. We worked through a tibial band injury with Mrs stinkwheel and setup/geometry is important keep your cadence high and load low. If you are clipping in, get cleats with the maximum possible float.

Have a look at the pedal stance width. You'd ideally have your feet roughly shoulder width apart and toes pointing slightly in so the outside edges of your feet are paralell. This makes the knee flex in a straight line.

Consider shorter cranks.

Mrs stinkwheel also trains on a fixie which works both sets of muscles round the knee but may not be appropriate for a prosthetic as it can be high load.

Update. Been tuning in the riding positon, happy now. well on track to hit my 250m a month target at 228. Been riding it on the middle setting. Find if I get a comfortable cadence going I get longer more comfortable rides.
The main thing is my knee is so much better even after this short time, if I have a couple of days off the knee is worse!
Glad I made the decision and got it now, well happy.

OGR.

Ebikes are interesting. I built an ebike from the kits. While it doesent have the poke of a 99 R1 this last week or so was a bit like the first joy of descovering motorbikes, right throttle hand turns and you go forward kind of smiles. Added to that the lack of speed cameras and ability to use the cycle infrastructure, i estimate across London its as fast as a motorcycle / scooter across town, 20p per charge, less hassel.

The battery technology is getting there but not quite, I think once these bikes do 100 miles per charge rather than the 50 ish now then ears will start perking up.

I'm used to touring on overloaded biks, but 34kg is alot for a bicycle , would be interested to know how you get on with that and the real world range.

Thats pretty efficient your setup then because I have just under a 1300 wh battery (52v) and im getting 40 miles (throttle only). I think im a bit thottle happy going to peak amps too much and not pedalling at all.

I met a guy on the road who said he had a 48v 60ah pack, it was a massive brick in fairness on his rack and reckoned 100 miles on the throttle.
