I have ended up with the Kalkhoff Ergo Impulse XXL i360 mainly because the company selling the KTM didn't seem very interested in selling me a bike! The Kalkhoff is very heavy and it would get me up the hills if it weren't for the fact that my legs aren't what they used to be. When they give up the ghost I stop and rest for a minute or two and then start off again.

What I can't understand is why, when I start off again, the bike seems to produce more power for a short period. If it kept on producing that level of power I would probably be able to cycle non stop to the top of the hill.

Yes I totally agree with you. If it had a more powerful motor! I have queried the problem with 50 cycles and am not getting any answers. Do not reply to emails. I am certainly a lot fitter but it is a struggle and it is taking the enjoyment out of the electric bike experience.

My Sonata will eat for breakfast all the bikes you listed...if you want hill climbing ability and stay legal then BPM hub drive is best. I am 6ft 1 " and 17 stone. The frame size of the Sonata is identical to the KTM Macina bold.
The most powerful of the KTM models are the Panasonic hub drives but KTM seemed to have lost interest in that model.
Having said the foregoing I am aware of brand awareness,I haven't bought any car aside from BMW or Audi....even though my senior manager swears by his Hyundai.
The Nuvinci hub seems to sap some power,you swop power for ease of change and range,
Buying e-bikes is a compromise.

Your bpm motor will not eat A bosch cx for breakfats,thats simply a lie.Its the other way around.I have both.

Another Mike on here had a similar spec Kalkhoff/NuVinci bike and had a similar experience.

I tried his bike and found it very lacklustre.

I wonder if the Impulse system software doesn't like the NuVinci's unique variable gearing.

That might explain why the bike pulls a bit to start with, but dies when the NuVinci action confuses the software.

How about £695 http://www.minibikecraze.co.uk/shop/bikes/zhenhua-sr-50cc-monkeybike/

Thanks Rob. I am now trying to compete with two 'geared' Kalkhoffs and am being left in the shadows. It's very hard work and certainly NOT the enjoyable experience I was hoping for from the Ebikes experience! Thanks again for your comment.

Thats a shame, care to help with a store name so we can perhaps offer some more training or see what the issue might have been.

On the Nuvinchi topic, just f.y. everyones i. its worth having a look at the new Shimano Steps drive. If you have this drive with the di2 electronic shimano shifting option a simple software update will allow you to set the cadance you want and the bike will shift for you. It doesn't have the infinite gearing of the nuvinhi, as the Nexus hub is 8 speed, but it does offer one of the best features of the nuvinchi for a fraction of the price.

not nuvinci related - but just noticed post by mike45

While searching the dealers, specifically for KTM accesoriess I have noted that some, KTM listed dealers don't stock spares/accessories but stated they had availability on ebikes in stock...One I emailed responded;-

''Unfortunately I do not keep those in stock. Generally we concentrate on
selling KTM's bikes rather than the accessories.

Kind regards,''

so I experienced the opposite of Mike45.

Luckily local KTM dealer in North Yorkshire has sourced the parts I wanted

It may be that because the Kalkhoff has a torque sensor, when you start off you subconsciously put in more effort and so does the assist, then you start to ease off and so does the assist.
