    I have a ghost racer 7g 4-stroke on a Metreon 700c cruiser bike (only frame I could find that would fit the engine) http://www.wayfair.com/Mens-700C-Metreon-Commuter-Road-Bike-8205-07DTJ-DYNR1080.html? My problem is there is no front brake (and it does not look like I can get one) and no type of suspension on it. What frames are out there that can accept a 49cc 4 stroke and have at least a front brake (disc preferred or later option) and a front suspension. I have a 44t manic mechanic type hub drive and with my (fat-ish) 250 lbs I am hitting 26mph on flat ground. A little more mid range power would be fun, as well...thanks

    I went to used bike store & got a front fork with v-brake posts for $15.

    that might work...its just an odd design...

    Definitely an odd design. 3 speed with derailleur? No front brake? WTF?

    Anyway, the frame appears to take 1 1/8" threadless forks, so you're in luck there. Most decent suspension forks are 1 1/8" threadless.

    Craigslist, garage sale hunts, you shouldn't have too much trouble finding an inexpensive fork with V-brakes. If you want a new one:

    susp fork: http://www.amazon.com/SR-Suntour-Fork-255mm-Black/dp/B004TN2FHK
    brakes: http://www.amazon.com/Promax-360859-V-Brake-Set-Black/dp/B007Y5GDZK/ (2 sets with matching levers)
    cable: http://www.amazon.com/Jagwire-Basics-Lined-Housing-Assembly/dp/B001CJYXKQ/

    All told, it's a bit expensive, but should be worth it. if you just want a standard fork:

    fork: http://www.amazon.com/FORK-700-HYB-CRMO-250xTDLSx28-6x30-0BK/dp/B002I7MAEM/

    Hope this helps!

    Will it fit? Mine is a 700c or is that a tire size? What if it is a 28" frame?

    that's the nice thing about used bike shop, you can walk in with forks in hand to compare

    The $230 largest size 26" Micargi Pantera 7S with front and rear V brakes will just fit an HS 49cc system with a little work like cutting the choke lever down and lowering your chain guard.

    For ~$85 more you can put a shock front fork with V-brake bosses that will take your forks brake arms.

    No kidding...

    Does that use 7-speed chain, or is it wide enough for #410 chain.

    That might make for a nice low cost jack shafted shifter.

    i just measured the down tube and it appears to be 24"

    700mm is 27.56"
    A 26" fork won't work, your tire would rub at the top.

    kc...do you have any suggestions? either with or without suspension...

    It depends on the fork design. My RockShox fork for 26" wheels fits up to 700c X 32 just fine.

    That will probably work just fine. I've also updated my previous post for 700c wheels. The suspension fork I found costs over twice as much as the one you did.

    aleman...do you have a link for the post? I NEED the front brakes and a smoother ride would be a happy benefit...

    If using V-brakes you just have to make sure your brake pads will adjust out far enough to reach the larger rim, but otherwise good to go.

    Mine has a springer and is why I bought it. I need to put the front fender back on but I have front brakes. Some said I would not get brakes on this springer. Yes in my opinion two wheel brakes are mandatory.

    Indeed, NO motorized bike is safe without a brake on each wheel!
    And the better they are, the safer you get!
    Trust me, it sucks when you don't have enough brake.
