Thanks, but no, that's the more modern Powertube. Mine would be https://winstanleysbikes.co.uk/bosch-powerpack-400-rack-type-battery-pack . That one is claiming to be in soon, I'll wait till it is. Also waiting to see in ebikebatteries might be an option; I know they can't do the latest Bosch...

Thanks. I did have one indication of sagginess the other day. It was still claiming 5 miles range and cut out; Sport (3/4) on a significant but not that steep hill. I'm keeping an eye on it, and also keep checking for not quite as silly as normal prices on a replacement. Winstanley at £440 for a...

Pending that, you should edit out his email address in your reply.

Should be fine. Odd that the link you posted in post #1 only showed 36v battery, no 48v option.

Our Bosch 400wh battery is showing signs deterioration. Maybe not unreasonable after 8 years (we got the bike 2nd hand about 2 years old about 6 years ago), around 6000 miles. Hard to tell, I'd say it was down to somewhere around 60%. Once deterioration starts to be significant is there likely...

The kit is sold as 36v. If you use a 48v motor you may need to change the controller and possibly the display. If you are lucky they will already be OK for 48v, but very likely not.

As matthewslack says, the 750w would not be not legal as a pedelec. Just to clarify: It could be legal as an s-pedelec/moped. You'd need to get it approved to ride on the road, then arrange insurance, registration, license plate etc. And you couldn't legally ride it off road in any publicly...

I agree that cadence sensor is probably most appropriate. However, her experience with the torque multiplier bike does not completely rule out torque multiplier. That bike is light but is a particularly low powered one, and it might be the low power that is the real issue.

One quick comment based on a friend's experience, it may not apply to you. She tried a good bike with a frame battery and really enjoyed the test ride. As we were standing on the pavement after she'd tried it people needed to pass. She found it really hard to move the bike aside because the...

I agree with that. Especially important is the ability to start on a steep hill. See Chris Juden's thread on Cycle UK forum. https://forum.cyclinguk.org/viewtopic.php?t=157613

Well, these days the 'call an ambulance or two' is already likely to take you past the 8 hours.

What planet do you live on?

You didn't mention how much you are doing the work and how much you are relying on the motor. That makes a huge difference to the range. Lots of people get 50 miles on a battery less than 1/4 the capacity of yours, but that's on a light bike that they ride pretty much like a regular one and just...

But on the other hand, also many years ago, I approached a T junction on my bike; no headphones, totally aware. I looked carefully left and looked right, observed a car coming, and rode out straight in front of it. Luckily the driver wasn't an AI robot but was extremely alert and she stopped in...

How far for two days, and how much assist? As saneagle says, the first segment tends to last a long time; don't assume the dropoff after that will be equally slow. Also, look at it when you are climbing a steep hill under heavy assist. The voltage sag will show a drop on the bars well before...

I think OP is new to the forum and doesn't know who's who, so I'll add: If saneagle says so and Woosh agrees then they will (99.9%) certainly be right.

Maybe the answer is the trolley bus. From Copilot: According to the web search results, there were 327 miles of trolley bus routes in London in 1933https://www.ltmuseum.co.uk/collections/stories/transport/londons-electric-trams-and-trolleybuses, when the London Passenger Transport Board took...

It may be that adjustment to (or even replacement of) the handlebars would help; how swept back, and is the sweep level or does if slope down a little towards the rear? Also handlebars quite high so weight is all on the saddle. (In addition to the suggestions above) For me, many bikes have...

We've got bells conveniently fitted, two quite sonorous but different ones on the tandem. I still often need to shout 'ding, ding' because it's quicker than ringing the bell.

Chances are the kit mod-motor is just as durable as a premium offering. If you go for a very cheap battery that won't have the durability; but a decent quality generic kit battery should.
