Having stripped it to a bare frame and motor for transport I think the frame is very heavy, the fork is maybe 1.5 - 2kg heavier than a good Rockshok. The wheels aren't too bad and the rest really is diminishing returns.

That sounds like a good plan, my MTB is 11kg unpowered, with something that small and a reasonable battery 15kg should be easilly achievable. A good hybrid with solid forks and road orientated tyres would be considerably lighter. Biggest problem I have with the Haibike is the weight of it, I'm...

That does look a bit steep, the constant battle to keep the front wheel down while stopping the back spinning is a major challenge on that! I suspect either of us would kill a BPM in short order! There are no hub motor e bikes going up the mountains off road around here. You do occasionally see...

I don't dispute any of that. As I said he stalled because he was in too high a gear when he still had two lower gears available. Off out now to ride my bike on some real hills with 32f x 40r gearing (not on max power though);)

That is all well and good and is fully understood but the 11mph is irrelevant if that is all the power that is available then that is terminal velocity. It is for me more about the second part of the OP where he says he didn't get up a steeper hill. No where do we have any indication of the...

Likewise for my Yamaha, I know a crank drive is not the best in all situations but I still cannot understand why the lower gears are not used. It is like trying to drive a car up a slow twisting turning climb in fourth gear, it will not do it. If you have a crank drive let the gears help, if you...

Can't say how insane I find overtaking cars on the inside. It is one of the major causes of serious accidents for cyclists. Cars and their passengers aren't expecting it ( and nor should they be ).They will pull in towards the kerb without looking to let cars going the other way pass in a tight...

But if it is a hill that causes you problems regularly then you should get your gearing changed so that you do have a low enough first gear. Having said that I'm still not sure the Bosch is the correct power unit for the OP.

You want to give me a Rio to test in the Alps against a Yamaha Haibike and see which I can kill first ;-) . Bearing in mind I can sustain 200W but still find myself in 32 front x 40 rear gearing going up inclines at 7kmh ( not using highest power levels to keep range sensible). Of course Yamaha...

As I said earlier he is still two gears above his lowest, why worry about 11mph it's irrelevant. As d8veh says it's all about torque, lower the gearing and sit there spinningyour pedals in bottom gear and torque multiplication will get you there. I was spinning up an Alpine climb this morning at...

So you still have two more gears to go at then, big difference between 26 and 34 teeth. You might well find with all of the electrical noise that your wireless computer won't work.

Just enjoy it, it will get better. :)

Bear in mind that if you have new snow over ice even studs can find it difficult to cope, when the top layer slides over the bottom layer you can still be in trouble. I'm not saying don't do it, just be aware that studs don't cope with all conditions well and are no better than normal soft...

I would hate the bars to be higher up, they look far too high for me as it stands. (all down to personal preference of course);). Give the brakes time to bed in and all should be fine.

If you don't have the legs then torque sensing crank drives aren't for you. Going up Alpine / Dolomites climbs like that can easily take over half an hour on an ebike. If you can't sustain 250W from your legs (close to pro territory for that length of time) then your Bosch/ Yamaha isn't going to...

Totaly agree but I was talking more about peoples expectations, experiences and requirements . I personally run soft sticky (ish) MTB tyres (Maxxis DHF 3c Terra compound on the front and a Maxxis Ardent on the rear)and don't expect them to last particularly long on my Haibike but I want all of...

Don't forget what is slippery to some is fine to others, depends how hard you are pushing them. It's the same as hills, one persons hilly ride is anothers flat daily commute.

When I replied I had not looked at Fin's profile and did not know she was female. In my work I spend a lot of time teaching young (mid fifties) women how to ski. I am very happily married and have no wish whatsoever to put that in jeopardy, I do however have some free time over the next couple...

Didn't see any professional cyclists in there anyway. Just for reference the guy that won yesterdays stage of the Giro d'Italia was putting out 1470W during the sprint at the finish. We know unrestricted ebikes are faster than non powered bikes as even pros struggle to put out more than...
