12,7Kg pedelec

[mechaniker]

my light weight racing-bike Total weight is only 12,7kg "ready to race"

Motor comes from "Shengyi" with 350rpm and only 2,2kg . The Motor I have ordered at my friend in China (www.woaczh.com)

basic bike is a Radon "Spire" which has only 7,5Kg and is outfitted with complete Shimano Ultegra-Group. Steering and shifter I had to changed into flatbar design because of my weight of 125kg. I can´t use race-steering

battery is from Phylion with 9Ah

Controller is sinewave and of course from “Lishui” . Controller is a special Lishui Typ integrated in the bottom of the battery-holder

I was unsatisfied with the usual displays on the market because on a sport-bike it should be small LCD-Display not one of these big screens in the middle of the steering.
I asked again my friend to send me some different LCD-Displays from different companys. I chose a small LCD-Display.

the bike supports me now up to 45km/h and even without battery it runs like a normal race-bike
very nice a low weight bicycle

regards
frank

Hi Frank,
your Radon Spire has a PF bottom bracket. Do you know if anyone successfully fits a BBS02 to a PF30 BB?
BTW, congrats on your beautifully built bike. Mine uses a similar kit but based on a Giant Defy 5.

I did this once but it was to much work. I had to push out the PF and then to drill an excentric adapter instead of the PF. and the BBS-Bottom-bracket must also change becaus the bike had nearly 90mm wide bottom-bracket and so on. I have a friend with a drilling-company in china and they have made it for me. I don´t like the BBS but I just wanted to know how much work it might be and whether it could be a business

difficult to say if it's commercially worth getting the adapter made but there is certainly demand for it.

so you prefer hub to the bbs? Have you considered the tangent drive?

Hi "cwah"
thats a powerfullfull motor I did´nt knew it before, thanks. I would be worried for the chain at such power.

In mountainarea it should make a lot of fun but I prefer Road and inside the law
