After 3 years and 17,700 miles, my Shimano e5000 is still without any crank play. I have a spare motor which does not need any dealer intervention to fit, and which crop up from time to time on eBay for under £200. I should be ok for a while yet!

You will not get another 5000 miles out of it. As soon as you get any play in the bearings, you must get it fixed, otherwise the damage accelerates. You can also get a bearing and seal kit and repair it yourself, though for the difference in cost, you might as well send the whole motor to...

My pennies worth: BEARINGS SERVICE If you went for a bearing service and from what you say above, around 15,000 miles will get you another 4yrs cycling before you're back to where you are now. In that time your bike may develope a different issue or indeed the battery (at £500?) may need...

After 4 years and 15,000 miles, my active line plus has developed a significant but not terminal amount of play in the crank bearings...these are my options: Send to performance line bearings for a full service circa £275. Run it do death, I'm thinking another year circa 20,000 miles....buy a...

Why did you replace the sensor? Is the cable OK on the other one? If so, you can swap them over. IIRC, there's a connector at the sensor end that burried in rubber sealant.

Hi Saneagle Thank you,i have replaced display, ecu, crank sensor and rear motor,am getting 41.3v out of 36v battery so only thing it could be is this cable i think.Would have to cut possible bad bit out and reconnect.Is there an easy way of re-connecting cables back together Thank yo Ian

It's almost certainly a cable connection issue. It might even be that the cable has been pulled at the sensor, so one of them has broken its connection. The sensor itself is optical, so nothing can go wrong with it, other than after a lot of use in dirty conditions, the dirt can stop it seeing...

Hi all I took my carrera vengeance e spec bike into an independent bike shop recently after losing faith in Halfords after countless visits.Anyway i was told the problem was an intermittent crank sensor.I'm not getting pedal assist but when i turn bike upside down and turn pedals i can hear rear...

Must have been badly out of fettle. Those old two strokes should just start straight away. Of course there are lots of issues in worn, and neglected 2 stroke engines. Bad petrol, coked up spark plug, wrong spark gap, wrong points gap, dirty points, duff condenser in points, bad ht lead, low...

I don't trust waterproofing claims made about anything. I've left my Bafang BBS01B mid-drive conversion standing in rain on it's kickstand for hours many times while out gardening, I've also cycled in sustained heavy rain for hours and 43 miles, my motor has also survived complete submersion...

Not me. I avoid rain if I can help it. Battery to motor cable requires some waterproofing, but rest is not necessary. You can do it of course if you want to. I was considering using threadlocker, but Seneagle said to whack spanner few times with a hammer, so I did just that.

Had anyone done anything to help prevent water ingress particularly with the cable from the battery to the motor? Heat shrink, dielectric grease, silicone sealant? My kit arrived yesterday and I have different connectors on the battery and motor which means two cable joins to weatherproof...

It's probably just the difference between a crank-drive bike and a hub-motor one. The hub-motor makes good power in the mid-range and gives fairly constant torque. The crank-drive makes the most power at abot 75% of it's max rpm, which for a Bosch is something like 80 rpm, which is a bit faster...

I have had the NCM Paris for a year and it did not go well initially .After 4 months the power delivery was intermittent . Despite Emails and phone messages left with the Supplier LEON CYCLE UK , they never came back to me . I did contact their only Dealer in the UK at Torquay who was very...

All good points guys, and taken onboard. I'm about halfway through the build now. The (250W) motor is on. The (48v 20Ah) battery plate is on, with a Grin Double Bob. The gear and speed sensors are installed. But I hit a (face palm) snag. I broke the derailleur!:( In my haste, threaded it...

Thanks that is very helpful

There isn't a ready-made solution. That bike would need special stuff, experience and knowledge to convert. It could be done. You can see examples on YouTube and various forums, all of which are probably illegal in UK. It has a very wide bottom bracket (165mm), which is probably too wide for a...

Telford looks nice and what cracking weather. I cycled through Telford 12 years ago on my LeJog trip - the city planners have been busy since then. The other guy's bike looks to be a proprietary system given the in-frame battery and so the crank drive motor is something like a...

OK, for those that think hub-motors don't climb, you can see how quickly I reeled in some guy on a crank-drive bike up a steep hill. That part of the path is very steep. Te rest of it up to the top, where you can see the kids playground is steep enough for an average guy to need an ebike to get...

You need to think about where you're going to fit the battery. The best place is low and central. The Paratrooper can't really do that. Yes it can be done, but wouldn't it be better to have it nicer if you can. Donor bikes are really cheap considering the cost of the kit. It's worth getting the...
