It seems to me that the power of a crank drive bike puts much more stress on chains and sprockets than on an ordinary bike. I find that an electric mountain bike does not need the number of gears that have evolved for non powered mountain bikes. On my 9 speed I often need to change up a couple...

We have moved away from the point. The modern powerful crank drive bikes need stronger e-bike specific chain, chain ring and rear cassettes. These do not need to be overly expensive. 7 widely spaced gears would be enough for most applications, geared in a way that there are no less than 14...

Hi Kelly, I replaced the saddle on my bike with a Velo one sourced from amazon that has proved to be very comfortable, well made and good value. Indeed so comfortable that I have put them on my other bikes. I do a 23 mile commute and have covered over 3000 miles so the recommendation is based...

The thing that worries me about changing to a Nexus 8 speed which I admit to being tempted by is that if you do get a problem you could be stranded and although I am certainly getting through cheap 9 speed cassettes, they are simple to change and when I get a problem with top gear (The gear that...

Hi Steve UKLSRA, I recently did two days Green Laning in the Peak District that certainly included a lot of steep rocky tracks. The optimistic leader took us (All 55+ except him on old/very old twinshocks Pre 1960 to1978) up hollingsclough which was fun! Worth a look on youtube. We also did...

I take my charger to work in my Ortlieb Panniers that are very useful for carrying other stuff and can be removed, carried about, and re attached very easily. I have a Haibike sDuro and the yamaha battery can be removed very easily and either carried by its carry handle or slipped in a pannier...

With reference to anotherkiwi's suggestion of swapping motors and relacing them, it might be even easier to just swap rear wheels if all the connectors are the same.

Hi soundwave, I agree, It is not that big a deal, I just put a new cassette on when I need to. At worst I have to drop down a gear, so I am not stranded by the road side. But I don't think it is just me, I think crank drive bikes put a lot more stress through the transmission and I am sure that...

Hi RobF, I ride in Surrey and there is a lot of sand. I thought the same and do try to keep the chain and transmission as clean as possible by regularly hosing it down and re lubricating the chain. My off road route is on the way to work and that can get the bike covered in muc and I don't have...

Hi anotherkiwi, Thanks for the link, Pinion looks very bespoke but on my quick look they are designed for hub motors. I can understand why as they take pressure off the transmission. My first electric bike that I still have was a hub powered bike and that had a basic shimano 7 speed that lasted...

Hi anotherkiwi, yes I know what you mean, I bought two cheap Shimano Alivio HG400 9 Speed cassettes from chain reaction in the sales at xmas for £10 each and outside the sales they are £15 and that is what I will continue to do as they wear out. But they seem relatively fragile and It just...

Thanks for the link soundwave, but nothing suitable for my cheap cassettes but worth a look. Cheers,

Thanks for that link soundwave, I think you may have posted it before but I was'nt paying attention. Just what I was asking for, though I may need to wait for the price to come down a bit! 450 Euros would buy a lot of cheap 9 speed cassettes. But it is good to see some thought going into a...

Another update as the bike passed the 3000 mile mark eleven days ago. No mechanical issues. My Schwalbe Smart Sam plus puncture resistant tyres and slime filled tubes are unchanged from new and doing a great job with no punctures so far. The back is wearing down but far from worn out and the...

Hi Fordulike, that's what I got them for, as a tough puncture resistant all rounder for my regular 23 mile commute with 13 miles off road, and I can't fault them after 3000 miles.

I am now over 3000 miles on mine, so they are certainly hard wearing. The back is wearing down but the front still looks re markedly good. About half my miles are off road and to date I have had no punctures. As Paul has said their strong construction makes them a really good road tyre. I run...

Also loving the humour. It is so nice to have a light hearted discussion about the use of a de restricted bike. It is not wolfie's fault that the legal limit in this country is 15mph and I am sure most people would have no issues at all if it was 20mph instead. For leisure mountain biking...

When my top gear (11 tooth with 38 tooth chainring) played up on my 10 mile road commute and I had to use the next gear down 12 tooth ring I obviously started going a little bit slower but had considerably more battery left when I reached home. Usually I would have 52% ish remaining and I had...

Sounds like a great ride. Years ago when my son was about six and my daughter a small toddler who travelled in a child seat on my bike together with my wife and a neighbour we rode the downs link down to Shoreham-by-the sea. My neighbour and I rode from our houses in Godalming connecting to...

I like to have mud guards on my mountain bikes and although you still get dirty it stops mud spraying into your face and eyes as well as a lot of the spray that would otherwise be drenching the motor and battery.
