Thank you. To be fair, I didn't want a throttle... I just completely underestimated how painful my hip would be trying to pedal.

Please excuse my very rudimentary diagram and obvious lack of technical understanding (I haven’t had chance to even separate the plug to count the pins because I’m currently out of action with covid and bored/thinking). My situation is this:- I’m 99% happy with my Boostbike conversion. After years of being told my frame shape was incompatible with the kits available, I was over the moon to finally get my bike converted. But I have a dodgy hip and this can “go out” at any time or place and for no apparent reason. When it does, pedalling is extremely painful and the conversion doesn’t include a throttle. So, can the kit be modded to include a thumb throttle? I’m not looking to be able to zip around at full speed everywhere, just be able to get home without having to call a taxi (again!). My overly simplistic thinking is that the only thing needed is a live feed from the battery to the throttle and a feed from the throttle into the wiring loom that bypasses the controller? Am I being totally naive thinking it might be this simple? Has anyone managed to fit a throttle and, if you have, how? Yours thoughts are invited.

Sorry, another q. If the controller is part of the mid-drive, do I then have to source a battery without an inbuilt controller, or will any downtube battery work?

Display? I like the 500c with the integrated buttons but I am wondering if there are any advantages by choosing one of the newer models such as the P850c or 750c (with BT)? Do the newer displays allow access to more tweaking options?

And is the controller built in with the BBS01B?

So the 44/42t chainwheel will turn/drive independant from the pedals?

Yes, sorry I didn't explain properly, I understand that I can freewheel but I meant going uphill (which is when my hip invariably plays up). It would be nice to be able to keep riding using the throttle without my legs having to move, instead of getting off to push.

I have an old injury that gives me a clicky hip, so I just wanted fit a kit with a throttle so I could stop pedalling every now and then and keep going. Obviously with a mid drive the pedals will turn if I used a throttle so I couldn't do what I need. I am only going to be using my bike for roads, towpaths and dirt tracks through woodland, absolutely no proper offroading nowadays. Are those model numbers all the same hub rebadged or are they each different? With regards to the cables, I had anticipated (once everything was fitted and working, that I would need to cut and solder/heatshrink everything to the right length, or am I being naive thinking it's that straightforward?

This isn't as easy as I had hoped. I can't find anyone with UK stock and looking on the likes of AliExpress etc it seems that very few of the stores will ship from EU to the UK (good old Brexit). But I am just getting more and more confused. I am settled on a rear hub configuration and the Mxus Xf08c looks like a good contender, using a downtube battery with built in controller. All of the kits are shown as including a separate (silver box) controller but no battery. Are there two types of downtube battery, one with built in controller and one without? Or do I just order a kit and a battery and then not use the separate controller?

Couple of questions. Is the number of magnets significant? If four would be enough, is it feasible to attach four neodymium magnets directly (using their own magnetic ability) to the bolts on the smallest chainwheel and then position the sensor accordingly? Or, in order for them to be attracted to the bolts would this mean that they would be incorrectly polarised for the sensor?

Looking at your photo vfr400, is there something (spacer?) between the magnet disc and the bearing? I have zoomed in but cannot tell. I have a scrap pas to experiment with (as per photo). Would I be right in thinking that I could Dremel out some of the centre so that the disc fits onto the splines, use a spacer to keep the disc away from the bb case and then tighten everything up (meaning that the left pedal is now offset by a few mm)?

vfr400.... No, you aren't wasting your time at all. I am a carer so I am up and down stairs frequently, in between typing replies and reading, so there is inevitably some cross posting. But I appreciate everyone who is replying and I am reading everything (sometimes in catchup).

And his explanation was that the sensor would only work if pedalling backwards. I didn't say anything to him but my immediate thinking was surely just reverse the two wires?

Nealh, fitting on the other side was exactly what I thought (and asked the question when I collected the bike) and he said impossible. Any chance of pics of yours please?

Nealh, I haven't purchased a kit yet because I still deciphering what I need to order.
