Living only minutes from Sherwood Pines I seem to be spending more and more time "off-road" just lately and my Xiongda Two speed equipped hard tail is taking a thrashing! Meanwhile, hanging unused on the garage wall is my full-suss full carbon Whyte E120. The bottom bracket shape of the Whyte...

Thanks everyone for your replies. The reason for my enquiry is that I have a chance at a 36V BBS02 but already have a 48V battery. I think I'll pass on it and resurrect the Q128c plan. Thanks again.

Hi everyone. I've searched on the net for a definitive answer to the question of whether it is possible to run a 36V BBS02 at 48V. Most people say no but a few say yes, but I've not found someone who has actually done it. Re-programming the Low voltage cutoff should pose no problem AFAIK...

Hi Dave. This looks like it might be a great motor for my project. I'm looking to build a more "road" focussed bike with a higher top speed than my Xiongda MTB. Around 22-24 top speed ideally, probably using a Spesh Cirrus or similar. Could be 700c or 26" wheels. If I used the same motor as...

Hi everyone. Some of you may have seen my XIONGDA build thread. Its a great bike, one of the best things I've ever built. But you can never have too many bikes so I am looking at building a more "road focused" ebike. Base bike will likely be a Spesh Sirrus or similar. Flat bar hybrid. The...

On Sunday evening we did a twenty mile route including mostly forest tracks and muddy field margins. Low gear was required for a few of the really muddy bits but the vast majority of the ground was covered in high gear. I set the PAS on level 3 which gives up to 240W of assistance. This setting...

Hi Grant. I just emailed them asking what the max RPM of my wheel should be.

Yes, it came with a charger. If you know what connectors your controller requires Jimmy can fit them.

Hi Nick. Contact at Insat was Jimmy. Tell him you would like the same battery that Mr. Lee had last week! Panasonic NCR18650B cells. He'll probably ask you how long the supply leads need to be. I received a printout graph showing the discharge curve of my battery. Capacity is quoted as 13.51Ah...

Hi Nick. Mine is a 13s4p but using PANASONIC cells giving 13.6ah, not the SAMSUNG ones which give 11.6. I've not flattened it yet from the first charge so I can't say much. The connector cables are certainly hefty. Geoff

Thanks for that. I like to see a nice tidy wiring loom. All the sheathing and heatshrink is sourced from VEHICLE WIRING PRODUCTS. You should see the fuel injection install on my kit car!

Battery arrived, charged and fitted. Its supply cables are super thick compared to the ones on the controller. Initial impressions are good. I have left the gearshift on AUTO for the time being. PAS is virtually immediate and powerful, even at level two. Level three PAS is very sprightly and...

I've just today taken delivery of a 13.6ah 48V Dolphin case battery pack from Insat International. £320 inc charger and postage. It uses 3400mah Panasonic 18650 type cells They sell on ebay but I went direct. It came with a printout from the discharge test. Here is their auction. The Dolphin...

Yes, it comes with a charger and it cost £320 inc post. Its a "DOLPHIN" type case. They offered a 17ah unit built in a bottle type case but it was too long to fit in my frame. I'll be doing a full report on my "XIONGDA" build thread.

I am presently awaiting delivery ( due tomorrow ) of a 13.6ah 48V pack from Insat International. It is made up using 3400mah PANASONIC 18650 cells. The chap building it up for me says he uses a premium BMS unit sourced from the USA and provides a full printout of the discharge test with every...

Iv'e just finished (almost) the wiring loom and swapped the Hayes brakes for some Avid Elixirs I had lying around. I tried a few different switchgear layouts and arrived at what you see. It includes a Kill switch in lieu of brake lever switches. I've ordered a 13.6ah power pack from Insat...

I did a quick trial build of the rear disc. The threaded holes in the hub are very shallow. Just over 5mm of thread. First attempt.. the disc was wobbling. Mmmmm. Brand new disc. New bolts carefully cut to length. What could be wrong? Well, there is a small radius on the hub that fouls the inner...

So the granny ring is off making room for the PAS on the crank side. The magnet wheel has direction arrows on it. I tested the little magnets with another magnet and found them all to be the the same way round, polarity wise. So I'm going to put it on the wrong way round so the same poles face...

So, for better or worse, I am embarking on my first e-bike conversion. Xiongda 48V 2 speed. Frame is a KINESIS MAXLIGHT. First job was to spread the rear dropouts to accommodate the wider axle of the Xiongda. This was easily achieved with a scissor jack between the dropouts and wooden wedges...

Hi everyone. Having researched online (mainly on this forum) I have ordered a XIONGDA 2 speed 48V rearwheel conversion kit. Due to the unavailability of a 26" disc brake version ( or indeed a bare 48V motor) I have had to accept a 28" kit from which I will strip the hub and refit into a MAVIC...
