Project E-Mini Bike, Using an Outrunner - Page 5 - RC-Monster Forums

If it mounts right up, why not? My system is probably 1300-1500w, so keep that in mind. I wouldn't expect speeds over 20mph with that though. Maybe 15-18mph. I would try to find a higher power system or use an rc system like I did.

My motor cost $55 and my controller cost under $30. A servo tester costs $5-10 and a pinion is cheap at mcmaster carr; probably $2.50.

Ok ya definatly gettin a set up like yours. Thanks for all your help man! Im just a little lost on the throtle thing you had going on with the different pots.

Metallover · 08.18.2009, 07:24 PM

Well, that didn't work out too well. It isn't a problem though because I switched back to the original pot. That works better then I thought because at speed you're not going to want to change speeds that much. It's like a cruise control.

I might pick up a kill switch so during emergencies and hard braking (brakes don't work that good anyway) I can press that instead if turning the throttle back. It would be faster and easier to do. Hey! The brake lever already has a saftey switch on it....

Haha, i cant wait to start building.

Metallover · 08.18.2009, 07:47 PM

God me either. I'm starting another project. Or should I say, finishing anther project. Whatever you want to say, I want to make a 12s lipo ebike with 20+ mile range. I can't wait. Just gotta put some hours in and then do some ordering...

After this i will do a go cart. its what i really want to do but this is just to get my feet wet so to speak, and im saving for a 1:1 car so money is, well i think i spend more than i make right now! LOL

Man hobbies are often spendy addictions!

So I'm thinking away on my killswitch. The switch built into the brake lever is "closed" (no current) when the brake lever is in the neutral position. When the brake lever is pressed down, the switch goes into the "open" position allowing current to flow freely.

I want to incorperate this into the bike as a saftey feature. I was thinking I would use a relay of some sort so when the brake lever is applied, it cuts pos voltage to the servo tester. I could also cut power to the battery leads into the battery. Just one 12v line off one of the batteries would do it. Either way the controller would have to re-arm, but I can live with that.

Is there an easy way to do this?

Kyosho · 08:44 PM

So you want when you aplly brakes hard you cant apply throtle? Im not sure other than your relay idea.
You could make some sort of clutch that disingages, lol that would be tricky though.

I can get a gas bike for $60 or an electric for $60. I would like the gas on and do a full gas to electric conversion or should i get the electric one just to use the throttle. I will be buying batterries from monsterscooter parts and i could just buy a thortle there. Im not worried about the extra $20 for another throtlle.

Metallover · 08.19.2009, 05:43 PM

The electric bike will be easier. You might be able to use the throttle if you go with off the shelf non-rc parts and it will come with half-ok batteries and a place to put them. It probably wont be done for you, but it will be easier to mount the motor.

If you use use rc stuff you'll be limited to pots and servo testers along with a few throttles priced around $50. There's a turnigy servo tester that uses a 5k pot, so the magura 5k throttle will work.

Kyosho · 08.19.2009, 05:57 PM

ya im using rc stuff. I think i will go with the elctric already bike. Thanks again for your help. Now back to your bike.

I rode it with a football helmet today.

Snuck up on this girl on here bike and scared the crap out of her!

If I can find an electric scooter I'm swapping over the parts because my father really hates this thing for some reason. He doesn't know I'm riding it and wants me to wear a motorcycle helmet if I do. WTF?

Kyosho · 08.19.2009, 06:05 PM

Can i have a link to the 5k throttle for the turngy 5k tester? Thanks.

Metallover · 08.19.2009, 06:13 PM

this should be it. http://www.hobbycity.com/hobbycity/s...Y_Servo_Driver

So any updates? I just picked up an electric scooter out of the trashv(No Shame so don't even try). It is complete, the only thing missing was the seat post. The 12V 12Ah batteries are toast, but I used a coupla 12V 7Ah and it works after I hotwired the switch. I am going to buy a set of batteries and ride it around for a while if it'll handle my fat a**.
