    Hi all,
    I'm a life-long bicycle rider. It's probably not going too far to say that it's humanitys noblest invention. I've even had some success teaching my daughters to love bicycles. I've been thinking about motorizing a bike for years. Even tried it with a lawnmower engine about 10 yrs back. Mounted it over the front tire, rigged up a lever to push the crankshaft up to the tire for a friction drive. It took off just fine. Enough to frighten me, as a matter of fact. But when I stopped my "clutch" didn't pull it away enough and it immediately ruined the tire. Oh well.
    Anyway, yesterday I ordered two 49cc two-strokes from thatsdax. The type that fit inside the frame with a chain drive. I'll rig up a bike for myself and one for my youngest daughter. If it all works out, then I'll order more to get my whole family going. If anyone would like to offer me their thoughts on pros and cons of this type of motor and, for that matter, the pros and cons of other types I would appreciate it.
    I'm a decent bicycle mechanic. At least I am able to replace and adjust bearings, true wheels, adjust brakes and so on. I have quite a bit of experience with that stuff, now that I think about it.
    So I'm looking forward to a lot of riding and I'm looking forward to sharing info and ideas with anyone I can. Thanks and so long.

    Hello, and welcome. I would've ordered the 65cc for yourself and the 49cc for your daughter. I hope your not looking for alot of power from the 49cc for yourself. Do some searching on the different engines around hear to give you an idea what to expect. But anyway you are going to have FUN and FRUSTRATION with these engines.

    welcome! don't know how old your "youngest" daughter is, but these things can go pretty fast! under 8-10 and you may need to look at somehow governing it. Probably wouldn't be too hard, just doesn't come stock!

    My daughter is 14 and pretty bicycle-savvy. So I see no problem there. Though I suppose I will have to watch out for her natural desire to hot-dog at high speeds. Still, she's pretty sensible. I'm sure she can handle 49cc if I keep a bit of an eye on her. In fact I probably need to worry more about her destroying the bike than destroying herself.
    Reading the questions I have been warned about one thing that I would not have thought of by myself; the chain tensioner loosening and bending down into the spokes. This is good; I'll know to watch out for it before I even install then engines. how do you suppose it would work to build a tensioner support that runs from the horizontal frame tube all the way up to the tube that runs from the axle up to the seat post? there would be no chance of that getting into the spokes. any drawbacks that I am not considering? Thanks.

    fair enough, 14 she should be just fine! Look around the site for tensioner ideas, there are tons of people that have built their own. At least one person has one mounted to the motor housing, via a hole drilled in the sprocket cover.

    Good to see another new motored bike fan join in.

    I'm pretty new here myself.
  11. 14 or 40 he or she better know how to ride a bicycle. Not just know how to keep from falling down. I mean REALLY know how to ride. It won't hurt if you can do tricks to your unmotored bike.
    Remember to tell your siblings that the engine is there not so you can fly but it's there so your bike can pedal for you. You try to go over even 20 mph your engine is screaming. Take it easy and cruise at like 10 to 15 mph with plenty of room to stop.
    Make sure you tell them too sometimes when you drop that clutch it doesn't always engage smooth. Every once in a while you let the clutch go when you start off it suddenly slows down instead of starts smooth. That happens to my bike sometimes.
    Oh and watch that kickstand as well. I took mine off. It kept getting loose for some reason and it took out two of my spokes.

    Thanks all. To RdKryton; that's a nice looking bike.

    I don't plan to use mine like a motorcycle. Trying to go 20 mph average would be too noisy and without ever even riding a motorized bike I can tell that that would destroy my bicycle. I'm looking for nothing more than an increase in my bike's efficiency. avoiding excessive sweatiness and cutting down on the time and effort to get up the big hills. I'm sure I can trust two of my daughters to be easy on their mbs, at least with a little coaching. I am worried about my third daughter and my wife; they are not actually speed-demons but they are not very good at using their legs as shock absorbers. They don't seem to understand the concept very well and they tend to slam bikes. but I'm pretty sure that they can get the idea if they can only get to like riding. I'm hoping that engine assist can help in this. Wish me luck!

    Just a minor comment on the learning to ride these bikes with motors, that's the easy part.
    It's the other road user's awareness that is a bit of a hassle.
    Just take care when approaching a vehicle wanting to cross, the drivers sometimes mistake you for a ordinary bike, therefore miscalculate the bike's speed factor and contiunue to drive across your path, then slam on the THEIR brakes.
    Even though we are doing 15-20 mph, the driver of a car thinks for a second you are peddling, then thinks, "wait a sec, something is not right" and is confused for a split second.
    At 14 years of age and not driven a car, it may be a bit difficult to identify what drivers go through to cross a road.
    Just be aware of this fact.

    The other fact is parked cars and all of a sudden sumwun opens their car door.

    All the Best and safe riding
