Like the "ebike" the media reckoned Simon Cowell had fallen off, which was actually a high performance eleftric motocrosser.

I know that on my Raleigh Motus, when I start off there is no assist until the "system" realises that I have started. Hence it can be difficult to start if I come to a stop on a very steep hill
COmbined with this is the fact that I have never - and can never see me - used 7th gear, even on a steep downhill. By the time I get up to that sort of speed (around 30mph) I am concentrating on not coming off and am more likely to want the brakes than to pedal harder!!!

Hence - loosing 7th gear and adding an extra low gear would be useful - which, of course, could be done with a different chain ring I suppose!
But that would mean that instead of spending most of my ride in 4th gear (the gear where I am doing around 15.5 mph) then I am in 5th gear which means the chain is at an angle between the chain ring and the gear


anyway - just some thought!

This is exactly what I'm talking about, on some of the e-bikes I see now (particularly the higher end 'trekking' bikes) they have a much better low gear. I'm also on a Raleigh Motus (GT 2020) which I think is a 38t x 11-34, compare that to this Haibike Trekking 5 High which is 38t x 11-51 and the difference in low gear is there. The high end gear is fine - I top out spinnning wildly at around 30mph though its rare I get to that so I don't need a higher gear but a lower would be appreciated.

One thing I found I was looking for was the power level assists, unlike some other e-bikes the Raleigh Tour won't boost beyond the power level (AFAIK) - you set the power by 4 levels (Eco (40w assistance/30Nm torque), Tour (100w/35Nm), Sport (170w/38Nm) and Turbo (250w/40Nm)) and thats what you get which I think is a great feature. I mostly use Eco, with Tour on hills or when carrying/towing. Sport and Turbo are saved for those steep hills but again I'd much rather have a lower gear than higher power.

Thanks - where did you get those power figures from?
WHen I used my Motus I generally find that Turbo is not much use and gives little more help than Sport - or even Tour - if I engage it on a steep hill
WHich, of course, means that I am probably standing on teh pedals and applying maximum power through them (for me!!!).
They do allow me to get up to the cut off point faster on the flat - but overall I don;t find they save much energy over Tour on flat roads

I have been looking fora better explanation of how the assist mode work but never found one!

BTW - I also find the "walk assist" to be useless - cuts in and out all the time and little torque so useless uphill - any ideas why?

There was a review here I found.

Same for me on wondering how it works to be honest, I've got the manual to read later as I have some things I want to look up. I've noticed for instance when I'm towing the power seems to be a bit 'wavey', I can feel it giving help and then not. I think it's just because the Active Line system is a few years old now and just works on the basic crank sensor.

Walk Assist I use a little but its not much help on anything other than flat, I've got a few steps to push my bike up and it's easier just to hump it up myself than fiddle with the assist.

Walk assist is fine, and very useful for train station ramps and even sand dunes.

Steep climbs you just have to walk very slowly.

I have 2 ebikes - and have 4 another
walk assist was very useful on all of them except the Motus - which has Bosch drive
On the others it would go up to the relevant speed (if it could) and hold there smoothly
as you say - useful on hills and ramps etc

But the Bosch one keep changing speed and/or cutting in and out - even on the flat
clearly the mid-drive system goes through the gears - which a hub drive system does not - but using different gears only affects the speed fractionally - and has no effect on the cutting in/out

Do other people with Bosch Activ-Line systems see this - or is it just mine??

I have asked the LBS and he can;t see any problems with the system - due to go back soon so I'll get him to check for updated software but I am not optimistic that the walk-assist will improve!

My MTB has the Bosch but it's the Performance line CX. Walk assist works fine, and is needed sometimes as it's a heavy beast. A little fiddly to use with the button pushes but doesn't cut out until the 6 km/h limit.

I have a Specialised e-bike with crank/mid drive. It doesn’t have a “walk assist” setting. I struggle to see how it would work, because the drive is in the BB, it would have to turn the pedals to drive rear wheel?, or, am I being dense?

No - that is what happens - the pedals don;t need to turn but it operates as if they were
as a result you can use it while riding - just very slowly!

in theory at least

There's a secondary freewheel ratchet in the BB. A bit of a pain as you've got to raise the rear wheel to lube the chain. You can't run the chain backwards via the pedals

Are you sure? Some people find the setting hard to find, though most often it seems to be entered by holding down the down assist.

Being a man, I have carefully avoided reading the instructions, so, no, I am not sure , but, it is possible to run the chain backwards via the pedals.

My bike is a Specialised Turbo Vada EL if that helps, it is a "mid drive", but, not a Bosch.

pity even they miss the fact that e scooters are illegal only stating you need appropriate tax and insurance

They don't, unless you rewrite the meaning of 'trial'.
