i need one with disk brakes and just like the one gebe sells with 36 spokes and disk brake ready, theres the link
http://www.bikeengines.com/orderpage2.htm

problem is that i ordered my engine and it took like 6 weeks!!!, i need a wheel fast because i need to use my motored bicycle to get around, its been a hard time trying to find a 36 hole rear wheel out there but so far i managed to find this

http://www.ebikestop.com/rear_26_de..._hanger_black_20_18db_silver_br_3x-WE2693.php

is that wheel strong enough for my 35cc robin engine???
any other wheels that other people have that havent bent or gotten messed up by the gebe 35cc engine???

thanks

I have a GEBE with the Tanaka 2-stroke 32cc on a schwinn - I dont know what you are doing to break spokes but I havent had a problem in over 2 years in all (with two different bikes).

Have you centred the sheave properly and there is also the trick of cabletying the spokes at the crossing points - that may help strength

The wheel you've provided the link to does appear to be made from decent parts. They are claiming the spokes at DT Dwiss Double Butted 14g and spokes don't get any better than DT's. But Folks around here seem to think that 12g straights are the way to go when you have the spoke breakage problems that you are having. With the Double Butted spokes your drive sheave will be clamping to the 15g section of the spoke, that might be a problem. Also the wheels shown have QR axles and I understand that this is a big No No for GEBE mounts. If you can find a good wheelbuilder in your area I'd have him respoke your existing hub and rim, with Quality SS spokes DT's or Wheelsmith 12g straights if they are available or 14g straights if not.

I am using Wheelsmith DH (for down hill) 13/14 gage single butted spokes. See if they have 13 gage straight or the DH single butted spokes and you should be fine. I have usually had breaks at the bend in my spokes and that is what the down hill racers are also finding. Most racing mechanics consider butted spokes to be strengthened not weakened from the butting. The spoke should be the part of the wheel that gives a little under loads and stresses. A broken spoke is quick, cheap and easy to replace. Hubs and rims are not any of those things to replace. Wheels are something to maintain and the best ones will not stay true for ever without some maintenance.

"Butted spokes are made from wire which is the thickness of the butted end but are intentionally cut short. The spokes are then hammered out to length, reducing the diameter of all except the butted end." http://www.central-wheel.co.uk/cwc/spoke_details/spoke_details.html

You might want to contact gebe. I know from others at least that the engines have been on backorder. Backordered engines take a while to get to you but a wheel should not. Id give em a call and express your concerns and see what they say. Maybe the gebe rep on the boards here could get you a quick answer.

I called our biggest local builder, whom Ive had make custom wheels for me in the past, and they said no way they can make me the wheel I asked for. So Ill probably pony up and buy gebes wheel at the same time as the engine kit.

I think they can send the rim faster. i have the 12g rim from GEBE and I am pretty sure that the rear rim will never be a problem with my bike. (As for the disc break think I just don't know).

Yeah, for sure. I think when prices for fuel topped 4 bucks a gallon interest in these engines exploded and the market wasnt ready for it. I know I didnt google it til it cost me 65 dollars to fill up my mazda 626. I remember when gas was 99 cents a gallon. LOL
