    Hi, I'm a noob. (Please see my introduction thread for details.) I have a awesome beach cruiser I want to motorize. I can't post a link because I am a noob I guess. It is a 'Electra Straight 8' bicycle. Would someone please google it and post a link or photo of one so I can explain my concerns with this build? The forum won't let me do it.

    I simply want to install a 2-stroke kit and ride, but it is a rather unique bike and I'd like a little advice from others with experience before I order something that may not bolt right up. It is also a very expensive bike (to me anyway) and I do not want to mess it up if I can help it. I am well tooled and plenty mechanically inclined, but do not own the expensive specialty tools needed to "custom fabricate" a lot of things and would scrap the idea if anyone thinks this will be a lot harder than usual.

    Thanks,

    Ralph

    Yes, that's it. Thanks a million, stilldoc! Mine is identical to that one except I have installed ape hanger handlebars for better comfort and a few more style points.

    Can someone recomend a quality 2-stroke kit that will bolt right in to this bike? As you can see, the lower frame tube going to the stearing head is bigger than most bikes. Also, the pedals are positioned about 6 inches farther forward than is standard. What about the cables that come with these kits? Will they be long enough for my bike's ape hangers? They are at least twice as tall as the stock ones in the photo. And the 3-speed Nexus hub. Do these cause any unique problems?

    Thanks,

    Ralph

    The throttle cables that come with the two-stroke kits are LONG so you won't have any problems with your ape hangers. Also since the majority of kits utilize a sprocket on the other side your nexus hub shouldn't cause any problems.(I am not 100% sure, as i only have seen the nexus in pics, but it looks the same). The "standard" two-stroke kits are designed for a "V" frame bicycle, like a normal mountain bike, so you have to drill a hole in some of the crusier type frames in order to mount the motor. I would recomend clicking on some of the links around the forum and finding a kit that fits your price range.(the motors are all the same design-wise, its just qaulty and a couple features that is lacking on the cheaper ones, i personally have a cheap $120 kit that i love)

    Thanks, JTG. When you say "V", do you mean V-shaped frame tubing as opposed to round? I'm not certain I want to drill too many holes in the bike.

    Also, the most important feature in an engine, as long as it fits, is lack of serious vibration. I want the smoothest one I can find if there is a difference. Customer support and spare parts being readily available are also big plus. I plan to pass this bike down to the kids.

    BTW, John, I love the Trail 90 in your avatar! I've owned 2. I sold the last one 14 years ago. It only had 900 miles on it and was in near mint condition. The fellow just parked it in a garage and threw a cover over it. I've spent the last 10 years trying to buy it back to no avail. I should have hung on to that one.

    Btw you dont have to drill a hole in the frame, theres a clamp type mount for oversize frames you can use, just look it up on this forum and you will see.

    What is a V-framed bike? Is mine a V-frame? It has round tubing.

    The way the down tube on that frame doesn't meet the seat tube at the bottom, you're definitely going to have to fabricate a front engine mount. You want the rear mount to sit flush on the seat tube; make your front mount to take that into account. This can be done even with hand tools and a cheap drill, as long as you're patient.

    Hi Ralph
    You should find everything you need here. Don't be afraid to ask ?? everyone here has been extremely helpful in my build. As far as tools and stuff, I have been able to do everything so far very cheap. Maybe not the ideal situation but I have done everything with my cordless drill and using vice grips to clamp things down to my bench because I don't have my vice handy. (thats a story for another time)I carry all the tools needed to work on the bike in a pouch that goes in my backpack when I ride. Good Luck, WELCOME!, and keep us posted on your success

    I got my kit from BGF on ebay for $105 including shipping. Runs really good and we will just have to see how it lasts.

    A "V-frame" bike is one where the seat tube and the front down tube are welded to the pedal tube. Your's is not a V-frame because your seat tube is welded to an extension tube further back than the pedal tube.

    Also, since it appears you may have a bit of cash to spend, you should look into a Sick Bike Parts shift kit to make use of that 3 speed Nexus hub.

    Sorry, I don't want to beat a dead horse but this is a ladies "V" frame. Tubing is round, and the frame style is illustrated here. No bends in frame members, just straight lines, point A to point B.

    I love dirt bikes and currently have a garage full. If it has 2 wheels and handlebars I'm all about it.

    The Nexus hub is SWEET. Unlike the many derailer bikes i've owned, which all had "issues" sooner or later, this Nexus bike has never caused me one second of grief and always shifts as smooth as silk with a tiny "click". It even shifts sitting still. Maybe it is just me, but I can't think of many things in life that have been as aggravating to own as bicycles with derailers. At first I worried about the Nexus being as durable as a derailer, but that is no longer a concern. It has served me well for 4 years now. I am not concerned at all that it will not hold up to being motorized for street use. The biggest drawback I can think of with the Nexus is cost, but it has been worth every penny to me so far. Plus, in my opinion, a bike just looks better without all that "hardware" associated with derailers.

    The only bike I ever liked better was my old 1950's Schwinn Typhoon with a 2-speed "kick-back" hub. It didn't even need a cable. You just snapped the peddal backwards to go from 1st to 2nd and back to 1st. Man, they should reintroduce that!

    Ok, I've got this "V" frame thing down. And a BIG thanks to all who have responded so far. I need all the help I can get.

    The Manic Mechanic engine mount will solve a lot of problems and looks good to boot. Thanks for that tip, Tinkermeister. I'll also check out this Sick Bike Parts shift kit. Gears will be nice if it doesn't break the bank.

    What about s m o o o o t h engines? I don't want a "rattle trap". Anybody got a preference?

    I usually like owning small 2-strokes better - as long as they are smooth. To me, the inconvenience of mixing gas and an occasional re-ringing is never as big a pain as dealing with regular oil changes. I'll just use expensive oil after break-in - to keep down the smoke - and have 5 gallons ready to go at all times. A 4-stroke is not out of the question, but considering the extra cost, it would have to have some serious advantages other than less noise and smoke, and a bit of longevity to win out.

    I really want to research this well and do it right the first time.

    Thanks again,

    Ralph

    I only have experience with one motor, mine is a RAW 50cc kit, and I don't have any vibration trouble at all. I know Venice recommends the RAW motors, too. I might have just gotten lucky with my first kit here, but the only odd thing it does is bog down a little at low RPMs.
