Nice project, love the bike. Maybe a pit bike seat would fit? They are cheap and easy find, should save you some time and money :)

Hi, I came across this crakset a couple of months ago and I think it looks really interesting. 3 gears, 179% gear ratio and should fit to most bikes. If I remember correctly it will cost $189 or $160 with the 15% discount. Homepage: http://www.efneo.com/en/gearbox/ Presentation video...

Really interesting, I'll be following this build. Do you plan to fit the motor to the chain stay? I think a belt drive on the left side of the bike would be a great setup. I'm working on my first build (BigHit+Cromotor), but I'm already planning my next one for which I'll probably use a...

Got the ball till sensor today and played around with it a bit. As adriftatsea predicted it doesn't work when vibrating. The small vibrations from the relays actually trigger the sensors when the module is places on a hard surface :lol: The relays seems really nice though. The MPU 6050...

It seems like my concerns about the ball switch tilt sensor are confirmed then... :? I don't know how the sensitivity potentiometer operates, but it will certainly not be as refined as a filtering software. A raspberry pi/arduino etc.setup will obviously open up to a whole world of...

That's part of the fun :lol: I just ordered this 2 channel tilt sensor: http://www.ebay.com/itm/331399882278?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I like that it has integrated relays (normally open and normally closed), which makes it easy to set up for a test. The...

Some more thoughts, sorry for the wall of text :) Maybe a progressive 'throttle decreaser' is overkill for a first test? If the alarm signal is connected to a relay that shut the throttle signal off, it should do the job. Maybe not that smooth though... I've seen opinions on how acceleration...

It seems like every person in this thread has a different view on what kind of system we want to make :) Correct me if I'm wrong, but I think you and I have the same approach; something like a progressive 'tilt cut-off'. The sensor doesn't increase the throttle signal when the front wheel is...

Interesting info! They're CNC machined though.

Finally the dropouts are fabricated! Got this picture from the manufacturer: I think they look good! But I regret that I didn't round off the sharp edges. I'll might file them down a bit when I receive them, I'll have to tap threads the holes myself anyways. Due to cost reasons I didn't...

That's a nice solution! Next time, I'll might try to make them myself. I've left enough material to drill and tap a pinching bolt. Does it really make that much of a difference? If so, I could talk to a friend that have a proper pillar drill. The manufakturer told me they will be done by next...

Yeah, I'll might try that next time. I think it would have been very time consuming to work 10mm steel though.

OK, I ordered the dropouts today! They're similar to the last ones I posted, but they extend along the chain stay instead of the seat stay. The price? $225 :o It's expensive to make custom parts! But as I don't have to pay for welding and heat treatment I guess that's OK.

Thanks for the caliper mount dimensions! Good point MadRhino. I made new carboard models today: These extend the swingarm back- and downwards in line with the seat stay. They are quite bulky and will weigh around 400-500g each. I'll might try to shed some weight off by adding some holes and...
