As most on here have indicated, from many years experimenting on the same route, I believe cadence is the significant influence in this. If you look at the motor curves, they’re mainly most economical when cadence is high, 70-80 rpm. 90 if you can sustain it, which is common on road bikes...

I had the PX and it dropped rapidly over 80, but had massive shove at low cadence. I think they addressed it on the later design.

I’ve had Yamaha and Bosch (gen 3)They are similar overall but each have their own character. The Yamaha was probably the most powerful and delivered high torque at low RPM, but the torque faded quickly as you spin up above 85 RPM. The Bosch is the opposite, good torque spread and strong even...

It’s all I have ever used on my road bike and mountain. I use it after every ride, after washing and to chase moisture from all the bearings and to lube the fork and shock seals. I know there is a previous post saying it’s bad for bearing grease, but I’ve been using it for years without issue...

I have the older level rr with the 500wh battery So it’s different, the level has a catch built into the cover to secure it. But looking at the photo I suspect these mounting points are to hold the cover on when the battery is inserted in the downtube, I don’t notice a catch on your cover. I’m...

I rotate and use the excellent evoc backpack, it’s expensive but reall well made. As others have said, once it’s on, you don’t notice it.

Can only echo what others have said on here. I have an old Yamaha px and a reasonably new (but the older gen) Bosch CX. There different but I like them both (emtb mode on the bosh is a real +), I agree the motor brand is not the most important, they all do much of the same. The Yamaha is now...

Ansmann make a timer plug for about £10 purpose built for charging. You can set it up to 8h if I recall correctly. It makes charging after a ride to around 60%/70% easy; roughly 2h on a 4A charger.

The evoc pack is designed for an ebike battery and has a solid back protector built in; so you don’t feel the battery at all and it all feels really solid. I ride some pretty rough fast downhill trails.

I took the plunge and invested in a new Bosch 500wh battery and the evoc backpack. It’s heavy when you put it on, then within a min or two you don’t notice it. It also has space for all my kit. No regrets, I can pretty much go anywhere I want now without worrying what mode I’m in. It only takes...

I’ve always been led to believe that the ratchet system is one of the best form of freewheel mechanisms our there, DT Swiss use it in their top hubs. The noise could just be a “design feature” rather than a fault. The variations in noise people are seeing is probably just frame design, some...

?it’s been a tough 1500 honest... at least my ribs (and the odd bent wheel) think so!

I’m running EX1 on the Mondraker and like it. Early days yet (only 300k on it ) chain checker and inspection shows all like new. Shifting is as solid as you can get even under power, which is one of its most significant advantages. There is the odd occasion (usually on a long firetrack) when you...

Yamaha PX (Haibike Hard 7) nearly 5 years old 1500km with no issues. Likewise for the 400wh Battery.

No problem, really happy with the 2 seals. They are well made with tight tolerances giving good confidence that the protection is superior to the original. I’ve had quite a few rides now in poor conditions and the whole area can be cleaned with a quick rinse.

This could be a potentially significant issue going forward. I was just looking to buy a spare Bosch battery and the Italy/Germany prices are the best around. However, I’ve recently noticed none of the EU suppliers will now ship to the UK because of new lithium battery shipping regs. We are...

I’m using the mudstop and the inner seal with the green Bosch grease. Although I didn’t get the wire at the time, so had a ? of a job getting the inner seal to go on. Not helped by the grease I put behind it. Ended up using a tiny screwdriver to let the air/grease out. Both are a simple but a...

Any news on the Bosch solution? I’m looking at buying a spare battery in the new year, but a bottle cage setup would be far more convenient. The Italian setup looks good, but I’m not getting a warm feeling on support looking at their web site. Besides, I’d rather support a UK business.
