Thanks for your comments everyone. I like the idea of the straight chain line but sounds like I'd be better off with the slightly lower torque of the bbs02 rather than the hd. Sent from my iPhone using Tapatalk

I'm looking at build a new bike with a mid drive unit, either bbs 02 or hd. I have a Nexus 8 hub lying around and I'm considering whether to use that or stick with external gears. I'd be interested to hear other people's opinions before I embark on this new build. Sent from my iPhone using...

Thank you

OK, I've got the motor apart (quiet easy really). I can see the planetary gears have some black grease on them. Does anybody know what type of grease this is? Can it be replaced with lithium or silicone grease or TF2 grease?

Thanks d8veh. Do you know where I can get any instructions on how to service this hub? It's the 8Fun CST hub. Not sure if you need more info than this.

I have an Oxydrive CST rear hub drive kit and the motor emits quiet a loud wining noise. Is there any way to quieten this down? Does it need any internal greasing? Sent from my iPhone using Tapatalk

Thanks for the replies everyone. I appreciate it.

T Thanks for the reply, I was going to say I had a 44t chain ring but then realised the BBS02 has its own chainring and O didn't know how many teeth it had. I would be using 26" wheels with 1.9 or 2.1 tyres.

Could anyone help me calculate the theoretical top speed of a BBS02 conversion please. I'm looking at the BBS02 750 watt version. The bike I'm looking at converting has a Shimano Nexus 8 Speed hub with a 20 tooth sprocket.

Sorry to hear your frame snapped. Just out of interest, do you think the extra weight of the kit made it snap? I recently did a conversion and had two bike to choose from. A Kona Roast which was made for jumping and looking around, and a Gary Fisher Big Sure which is a very lightweight cross...

Ah that's good. Thanks for the info. I read the new manual on the Oxydrive website and it said the battery warning on the display would go to zero then flash when low. I now know it doesn't. As far as distance goes, I didn't get very far as my battery wasn't charging so I set off probably half...

I was riding my CST kit today and it went from 2 bars of battery to 1 bar and then cut out and displayed an error code 6. Is this normal? I thought the battery level would go all the way down to 0.

Frame batteries are now becoming more popular and appearing in more kits and are mounted to the frame using the two water bottle mounting points on the down tube. I wondered if anyone has attempted to add a second mounting point to strengthen the arrangement, as it does seem like a potential...

Thanks for the info.

Oxydrive CST HT Kit on my old Kona Roast. Almost finished. Just need brakes and to mill down the 44t chainring to fit (36t chainring is installed temporarily). One question: I've been playing with the speed settings and I've noticed that the max speed when using the throttle is linked to the...

Did you use stainless or alu riv nuts?

Is the cassette rear hub 9 or 8 speed compatible please? Rick

Thanks, just need to sell my Volt Metro now to recoup the cost.

I had to buy it just to prove you guys were right
