I finally modified my old MTB (a 1996 BMC) with a BionX PL-250HT rsp. P350. The Bionx controller was defect so I connected the phases and hallsensors to an external BMS Batteries controller S12SH. The accu is a 15S 6AH. The problem with the S12SH is that it is a 36V/48V controller and...

Nice bike! My bike was stolen 1month ago. :evil: :evil: :evil: Yes this happens also in Switzerland... The god thing about this is that I started a new project: a 20year old MTB with a BionX HT250 with external controller. :) cheers

4500km so far, no big issues exept a fuse contacting problem... Have changed the tires for the more silent Continental Race King 2.2 at front and Maxxis Holly Roller 2.4 at rear. Changed the fork for a Marzocchi All Mountain 2, with 150mm travel. cheers

I balance them during charging. All cells are wired to the charging connector and then charged with 4 separate RC chargers with 4 independent power supplies. It is still in the provisional state, made quick and dirty ;-)

yes the bike still runs well, has done 3000km so far without further problems :D

My Bike with a HT3525 @ 20s and 46A max. batterie current (measured) what gives about 3kW max. output power wheelies quite well. Not real powerwheelies (or only at low speed and full batteries) but it has enough torque to lift the front wheel up to maybe 30km/h without pedalling but with heavy...

The sicker on the 350W motor says 36V 300rpm. Is this the freerunning rpm or the max. running rpm under normal condition, which would by about 36km/h or 22mph?

Any news with the BionX project? I have also a defect PL250 HT (which is the P350) here and would be interested in the KV rating rsp. what rpm this motor would do on 48V with a crazyman contzroller... cheers

No I'm not one, but thanks anyway dude :mrgreen: It is actually much easier with an powerfull ebike than with a motorbike! Because you have more control with the rear break on the handlebar than on the footpeg. DO NOT WHEELIE UNTIL YOU FEEL COMFORTABLE WITH THE REAR BREAK! When wheeling...

Yes you have to use an unblock sw or watch it on vimeo: https://vimeo.com/84250453?utm_source=email&utm_medium=clip-transcode_complete-finished-20120100&utm_campaign=7701&email_id=Y2xpcF90cmFuc2NvZGVkfGI2Nzg5ZjU5ODBhZWFjNmZjNzZmM2YyNWYzMmIzNTcyMTY5fDI0Mjg1NzY3fDEzODk4MjU4NDR8NzcwMQ%3D%3D Gruss...

the bike has now 1800km on the counter and still runns great :P the real km's maybe even a bit more since the counter is mountad on the front wheel :mrgreen: here is a little wheelie video that we made 2month ago: http://www.youtube.com/watch?v=4FkG_eyuN4w cheers löru

I finally set the speed to the maximum 120% and the current to 28A. This added quite a lot of acceleration and the topspeed is now steady 65km/h in normal riding position :-) Then finally measured the real input current of the controller: It pulls max. 46A which is 66% more than what was set in...

Short update: I did not recharge the batteries enough during the winter and therefore 4 packs are death. The other 4 packs could be saved and they now work in a skateboard quite well. Since the 4.4Ah 15C Zippy’s are no more available I changed to 4Ah 25C Zippy Compact. Unfortunately they are...

Hi Paul, haven't seen your post when I wrote mine... The gap between your 5.5kW Intens and a 250 4-stroke is probabely a bit smaller than my 2.5kW ebike to the 610 Husky that I ride normally ;-) But i share the same opignion what the ebike riding concerns, its quiet and therefor you better...
