Re: Bosch active line based bike suitable for touring?

We have an older *2016 model) Motus 7 speed hub; with previous generation Active Line. Very enjoyable. According to specs that had 43mn torque, the new (2018) one has 40mn, and the new Active Line Plus has 50nm. The torque figures are not too important as they are multiplied up by the gearing. I'm a...

I endorse that: I've never used Jimmy, but (almost?) everybody on the Pedalecs forum who has praises the service and value.

Re: It's very wet! - submerging the electric motor in floodwater

My Riese and Muller Supercharger got a similar soaking when I rode through a flooded dip in the road. I went on to cycle another 25 miles no problems so I wouldn't worry. I'm afraid that if there is water ingress it could take quite a long time before the issues really start to show. Hopefully they...

We rarely have one, but when we go on holiday we usually buy a local newspaper to get a feel for the place, and then to stuff our boots with once we've found the local wet spot.

Re: best conversion kit

Another other thing whichever you go for ... make sure you install it with the motor wire leaving in a downwards direction to prevent/reduce water ingress.

Re: Charge battery from car socket

Most ebike batteries are 36v or 48v; a few 24v. So you would need a converter of some kind; probably to 240v ac then use regular ebike battery charger. An ebike battery is typically 10aH or more, so a 36v one would take 30aH from a 12v car battery even not allowing for losses. Typical car battery is...

Re: best conversion kit

Check Cyclotricity reviews; some positive but certainly not overall glowing. General option (mainly on pedalecs site) is that Woosh I mentioned before give much better service. They don't appear to be significantly more expensive ... make sure you compare like with like, especially battery and contr...

Re: Crank drive query

I'm not sure about the front chainset. It may be that the bottom bracket on the Bafang isn't wide enough to fit a triple. You don't necessarily need such a wide range of gears with electric because of the help the motor gives. That is especially true with crank drive, as the motor is benefiting from...

Re: Add-on e-bike conversion kit - Swytch or eBay kit?

A bike motor is more powerful than the average cordless drill, at least its ability to generate continuous power. (I can't see continuous power ratings for drills in a quick search). The bike battery has much higher capacity. eg a £50 B&D comes with 2x 1.5Ah 18V battery, 54wh. A typical lowish e...

Re: Replacement battery for e-bike (different voltage and Amp hours), will it work?

The motor would probably be OK at 48v (if used with care). However, the controller would almost certainly need to be changed, and maybe the display unit. You would be fine with a battery of a different Ah rating; but it does of course need the same mechanical and electrical connections. If you ask o...

Re: Do E-bike riders get more exercise than regular cyclists ?

Last week, I decided not to charge my battery even though it was down to 20%. I wanted to see what the actual range was; the estimate on the control bears little relation to reality. I got 108 miles from the 400w battery, and the lights still worked even though the motor didn't. The upshot of this ...

Re: When is an Ebike not an Ebike?

Certainly not a pedalec. No pedals, the motor looks like an ungeared direct drive and almost certainly above 250w nominal, and 20mph. Therefore cannot be driven without licence/tax on UK road as a pedalec. It might come under the mobility scooter rules? p.s. no, certainly breaks the 8mph max. https:...
