Does raise the question, again, of why there's no UK/EU supplier equivalent of BMSBattery and Greenbikekit that can source the most common 8fun and Cute motors, wheels and bits and pieces. Even on eBay. Going direct does work, but shipping takes ages and costs a lot. And you always seem to get caught on the VAT/Import taxes. Or is there a reliable European source and I just haven't found it yet?

Is there a UK supplier who can source the Cute/QBK 10 CST in a 700c wheel?

. Ah. I assumed it was an Aurora as the thread was originally about that. But perhaps not.

Go and check BMS Battery or GreenBike, http://www.bmsbattery.com, http://www.greenbikekit.com/ and look for a battery of the same size and shape, 36v, LiNMC. As far as I can tell they come in two lengths for 36v-15Ahr and 36v-10Ahr. But the locking mechanism and extrusion hasn't changed so it should fit straight into your existing rack. As above in the thread, you may end up having to change the plug/socket connection to the controller. eg this one. https://bmsbattery.com/ebike-battery/162-36v10ah-li-ion-alloy-05-case-ebike-battery-pack-battery.html or this one. https://bmsbattery.com/ebike-battery/232-36v15ah-li-ion-alloy-05-case-ebike-battery-pack-ecitypower-battery.html

Interesting that on endless sphere, the first comment recommended the Q128 with the usual "more is better" view. My current ride is an Alien Aurora with the big BPM motor. What I'm trying for is a better quality bicycle that's lighter and more discreet but with about the same performance or a little more. And I was encouraged by a recent sale ad on here for a Q100CST wheel. I can see I'm now heading down the rabbit hole of research again. Not least because the various suppliers don't necessarily have all the options available. This week. Next week they might. I was planning on getting the controller and battery from EV3EM as they do suitable 6-FET controllers with upgraded FETs for a ~50v system.

Decisions. Decisions. Which would make a better base for a stealth 48v-15A rear drive motor on a bike with mechanical 160mm disks and Shimano Acera 9sp rear mech? The Cute/QBK 10 CST using the existing 9 speed cassette, or the Bafang/8Fun SWXH with a DND 9sp freewheel. The Cute has a LHS cable exit which might be a bit neater. And the CST using the existing cassette which might fit and work better with the existing drop outs and mech. Conversely the Bafang might be more robust and cope better with being overdriven. There may be some differences in disk clearance, spoke dishing required, drop out width and so on. The bike is a Genesis Tour de Fer. Road touring bike with 700-35c Marathons. Anyone got any direct experience of the comparison?

Well I fitted a 13g one. We'll see how it works out. Probably better than using the old one with the end turned over into a U.

The 13g tiller spokes turned up and they're just right except it looks like the originals are 12g not 13g. I'm drawing a blank on finding another source. There are a couple of places in the USA that do Sapim 12g for BMX but only in short lengths. johnc46 the head popped off. I've PMed you.

It's always slightly puzzled me about this that lighter weight spokes are less likely to break.

My much loved and much abused Alien Aurora has broken a rear spoke. These seem to be heavy duty BMX spokes and look like 194mm, stainless, possibly 13 gauge or even 12 gauge. My local bike shop can normally supply custom spokes but his thread cutter/roller doesn't go up to that diameter. Given that Alien has gone out of business, here's the questions. Does anyone know the actual gauge, and does anyone have any ideas on where to get a replacement? [later]. Looks like 13g 2.3mm straight, 190mm, 5mm nipples. So I've ordered 6 from here. http://www.tillercycles.co.uk/page2.html#Anchorleader13g I'll let you know if that worked.

The battery came with the plug. I used the existing controller that came with the bike.

Happy ending to this. I bought this from BMSBattery. 36V15Ah Li-Ion Alloy Shell EBike Battery Pack - BMSBATTERY The mount is exactly the same. It slides onto the existing Alien Aurora rack plate, the lock pin locks into the same hole in the plate. The one catch is the need to remove the panel mount connector and replace it with the kettle plug that came from BMSBattery.

Sorry, we did this once before. The battery uses a panel mount female socket. What's needed on the bike controller side is a panel mount shrouded male and that's the one that's hard to find. [later] Found it. Schurter Group - Home - Components - Connectors - Connectors (Inlets/Outlets) - 6048

http://www.bmsbattery.com/36v/232-36v-15ah-lithium-ion-electric-bicycle-battery-pack.html The design is almost exactly the same as the original, just a bit longer. It fits onto the same base plate and the lock engages in the same way. The connectors are in the same place at both ends and the only real difference is the use of a standard kettle plug rather than the weird plug used on the original.

Yes it did. It's a cable connector, but it fit neatly in the hole left by the stock one. Even if BMS hadn't supplied they're easy to find from Maplin or such like. What's nearly impossible to find is a panel mount female plug.
