I'm wondering about getting the 5-speed Nexus rear hub of my Gazelle e-bike (belt drive, disc brake) swapped for a 7 or 8-speed one. And I have questions ... 1. Assuming I could find somebody to do it (rear wheel there and back by courier), could anybody take a guess at a likely sort of cost...

Here's a picture of my Nexus 5 hub after being put back together as per advice received here, YT videos and the snaps I took whilst taking it all apart. T'other end of the axle is clamped in the vice. Wheel turns freely clockwise but not anticlock. Have I cocked up or do I need another coffee?

Sorry chaps, but the guts of my hub have now been soaking in ATF for most of the day (with occasional agitation) and the plan is to let it drip off overnight so I can reassemble tomorrow. In anticipation of this I've been checking online the oiling procedure and I'm a bit puzzled by one aspect...

I'm finally recovered enough to make a start on dismantling my rear hub in order to oil/grease it, and I've already hit a snag with which neither Google nor the data sheet is much help. I've got as far with the (belt) drive side as in the picture. It's not obvious to me how those two lugs...

I'm going to have to do the lubrication of my Nexus 5 hub internals in the kitchen, which is obviously a bit of a domestic minefield. What's my best bet for cleaning off the existing grease and oil? I can do that outdoors, so something in a squirty can that I can spray on and work in with a...

I'm just about recovered enough to start getting my act together to service my Nexus 5-speed hub, so ... do I really need to use genuine Shimano oil and grease? If not, what should I be using instead? No bike shops hereabouts and postal delivery is crap, so preferably something I can get from...

I have a 2023 Gazelle Grenoble C5HMB with a Nexus 5 rear hub and the usual twistgrip change. The bike's done just over 2600 miles. Every now and then, and for no obvious reason, it decides not to change up. Say I start off in 2nd, pause my pedalling and change to 3rd, nothing will happen...

Morning all. Pics are of my 2023-model Gazelle Grenoble C5HMB. Can anyone please tell me how to take up a bit of slack in this headset? (The slack is in the headset, btw - not in the monoshock suspension :))

This relates to a Nexus 5 setup on a 2023 Gazelle Grenoble C5HMB. How stiff should the twistgrip be when changing down? Obviously it will need more of a twist going down the gears than up, but mine needs a fair old amount of twisting compared to the 8-speed Nexus on the wife's Batavus (which...

I have a 2023 Gazelle pedelec with belt drive to a Nexus 5 hub. It's done about 1500 miles and has recently started acting up when changing gear. Sometimes when I change up, all that happens is that the shifter moves to the next highest gear indication, but the hub doesn't change gear...

Bike is a 2023 Gazelle Grenoble C5 HMB and I need to check that mounting bolts are tight. Question is, how do I get at them? I guess I take off the left-hand crank then undo the screws holding the plastic cover on, but if anybody knows what happens next that would be helpful! And while...

I have a 2023 model Gazelle Grenoble C5 HMB, which has belt drive to the Shimano 5-speed hub. The belt's started "creaking" intermittently from time to time for no apparent reason. I'm unable to decide what the rate at which it "creaks" ties in with, but it seems to vary according to gear...

Just out of curiosity ... White step-through frame, rear hub motor, black battery behind seat tube, red/pink throttle(?) button on r/h of bars, black rear carrier with rat trap, pink plastic "wicker" basket on the front, European-style noseless saddle. Recently bought new on Facebook, apparently.

I'm using the current version of E-bike Flow with a 2023 Gazelle and an Android phone (Samsung galaxy A14). All is good except for one mystery. At top left of my home screen, alongside the time, there's always a bicycle symbol. When i drag down, it says "Keep e-bike connected". Does...

The Schwalbe Active Plus tyres on my ebike have arrows on them indicating the correct direction of rotation. I can understand it making a difference on a motorbike or a car, but why does it matter on a bicycle? What is it about the tyre construction that dictates which way round it's fitted?

by way of a repair/maintenance stand when it comes to step-through pedelecs? We have a cheapo stand from Lidl which works well enough with bikes which have a crossbar, but I was just wondering what the trade uses instead where there's no crossbar ...

The Yamaha motor of the wife's 2019-model Batavus E-go is well past its best-before so it's time to see about getting it fettled. What sort of a job is it likely to be to remove it? Having spent a large part of my life rebuilding motorbikes it's not the mechanical aspect that concerns me but...

As in ... The wheel still runs dead true and is still exactly concentric with the hub. Can I get away with carefully squeezing them straight by means of a small steel vice with ally jaw liners?

I have a new 2023-model ebike which has a Bosch Performance Line motor rated at 75Nm torque. Seeing as how the maker's bumph doesn't tell me and there seems to be no label on the motor, how can I tell if it's a BDU450CX or a BDU490P?

The wife has a 2022 Gazelle ebike with 5-speed Nexus hub and Tektro discs. Because of the steep hills round here and also the way she uses her brakes, I'm thinking ahead to the point at which it becomes obvious that her rear disc in particular is past its best before. So ... Q1 Is there a...
