Re: An Advanced Friction Drive System

sounds like fun, now you just need to work on making it a real stealth thing, so people just think your an awesome rider! maybe mount it lower just under the bar its currently on? put the batts inside the frame, down the seat post or something and your good to go :D maybe cover the drive system up w...

Re: My "fast and furius" no hub e-bike:)

not too quiet, but it seems to work well :D i must say, that second video must have been some of the best camera man skills of the ebikes ive seen, most have been a guy holding it in one hand and riding with the other... did you make up a mount for the camera or what? seems like you had some fun on ...

Re: Minimizing chain noise

so, if i was going to walk into my local store, to get a strong (peaking at around 7-8hp from stall) and relatively quiet if possible chain, what would be a good brand and/or type? people are throwing numbers around that i have no clue what the correspond to, but im sure if i have a list of possible...

Re: An Advanced Friction Drive System

I'm with you Todd. Totally agree that if you want to push more then 1.5kW, a knured roller like your setup is a better option. I am currently getting a knurled sleave machined up at the moment but I need a lower kv motor to test it on. Hyperion and Scorpion are actually tied up together now and as ...

Re: 5000w Norco dirt jumper

damn, nice build, kinda like what im starting now, except im using a giant stp1 frame, and, jester will like it, a "real" motor! :D good to see you frequently get 60+ km/h out of yours, i was told to expect something like that was stupid as i would blow the electrics up almost instantly......

Re: An Advanced Friction Drive System

sounds awesome. a small compact unit like this would sell if you can convince people it is efficient and get them off the friction idea, im new so didnt know anything about them before, but im sure alot of the old hands have something to say about them.. a quick question though, how would this setup...

Re: LiPo battery care and basic information

ok, cells, bms and the charger are all made by headway. so can anybody tell me the output voltage of the charger (linked in post above) and what the bms is capable of doing? need to know if i have to buy the charger or if i already have a capable supply so i can put the money towards a better esc. t...

Re: Even Newer 4 to 24-cell Battery Management System (BMS)

oooh, this is a more specific thread for my question: when charging with a bms, what does a charger like this: http://www.e-mtb.com.au/36v-5a-lifepo4-charger-w-alloy-case-p-239.html do? its a headway brand, apart from that i know nothing about it... does it just give out X volts and Y amps, and the ...

Re: An Advanced Friction Drive System

oh ok, thanks todd, i didnt realise the pressure was variable onto the tyre, i thought it was an on/off sort of thing. i just thought that with a smooth rotor onto the wheel it would slip far more easily, but apparently not. sorry for any noob questions, im trying to learn about the systems :D i mus...

Re: Friction drive outrunner setup

dont think friction is for me (daily offroad, wet grass 4 months a year, plus i want mad speed and acceleration, something i dont trust the tire to handle) but i like your design, small and neat, the kiss principle in action. how far does the motor stick out from the bike, or is it small enough to f...

Re: An Advanced Friction Drive System

so did i just read that you are a mech engineer? if so, ill assume you did the calculation as to the resistance loss. off the top of my head i would think that the resistance would be huge, either you would get slipping or the motor would use a lot of energy to overcome the friction onto the tyre, w...

Re: LiPo battery care and basic information

ok, i have a question about charging, not lipo specific, but still lithium cells... i couldnt find a more specific thread. i am fully versed in all the safety, voltage, balancing, etc stuff regarding the cells, been using lipo for several years, but i am thinking of getting 12 lifepo4 cells with a b...

Re: will these rc electrics survive?

Just remembered. Look into getting a Cycle Analyist. You need the power wires to be as short as possible. You can remove the shunt from the watt metter and remote mount it, but trust me having a CA is the way to go. Also make sure you add extra Capacitors to the ESC, search for the thread on it so ...

Re: will these rc electrics survive?

Hi, Castle HV (HV160 for 130 amps) series are best for maintaining sync. so you think i will have a problem with the sync? a small amount of cogging (second or two) i can deal with. gwhy, does your motor get hot at all? what kind of amps does it draw, if you know? as for the sync, do you think the ...

will these rc electrics survive?

Ok, hey guys, im new here, been into rc for several years now, and was referred to this site about building an ebike. So basically i was wanting a lightweight high powered bike (not too powerful compared to some of the systems i have just seen) of about 3kw. i have asked all my rc go-to guys about i...
