Posted by: Dave TITLE: AGE / VALUE:   bike motors
I am wanting to get a motor for my bike but am confused about friction drive vs. belt or chain drive kits. Can someone make a recommendation? I have looked at angel wings, island hopper and golden eagle.

You would probably be wise to follow Rif~s example, and go with
the friction drive type. If you blow your engine, you just
unbolt the corpse, and you have a normal bike again.

My personal preference is for chain drive, just because it~s
more manly, however, that~s my macho side coming through.
You can get friction drive 4-cycle engine setups, which aren~t
as noisy and smelly as the 2-strokes, but manly guys are generally
noisy and smelly, so 2-strokes are a good match in that respect.
I~ve designed a stainless-steel exhaust system for Mr. Moto,
my kustom moto project. It will have a 2"X 12" tubular fiberglass-packed
"muffler" which should deliver a richer sound than the typical
2-stroke engine, without losing too many of those kool and nasty
decibals.

No problemo! Glad to be of assitance.
As far as the noise level, well it~s kinda loud. I mean it IS after all a weedwhacker motor. the Island hopper kit utilizes a 49cc Tecumseh two stroke engine.
I let a friend of mine take the bike for a jaunt, and when he came down the street at full bore it sounded like a mutant hornet or something! It was actually cool to see it from the perspective of the bystander for once...
This motor (stock out of the box tops) out around 25 M.P.H. I~m shooting for 35 top speed, and cruising around at 30 average.
Oh yeah, one problem I did have with this kit is the twist grip throttle- It sucks. It~s absolutely the bottom line cheapest thing that can possibly be had. It never worked properly and eventualy it severed the cable. I don~t really care for the twist grip throttle assy. on motor bicycles anyway so I put my trusty old ~trigger~ type throttle assy. on the new motor kit. No more problems and it~s much more comfortable...
But overall I really dig this kit!

Thanks for the info, Rif. I am a middle-aged man and not at all mechanically inclined. I want to use the bike mostly for fun and recreation. I live in a mountainous area but there are also a lot of flat areas to ride here on top of the mountain. The bike I want to use the motor on is a mongoose mtn. bike. If whatever I get works well enough and seems reliable, I would like to go maybe 5-10 miles. How loud are these bike motors? About like a weedwhacker?

Hi Dave,
there are many different factors to consider when motorizing your bike. The chain drive vs. friction drive vs belt drive is a debate or question that~s been around a lot lately.
I personaly have had three motor kits, all were / are of the friction drive variety. the one real down fall of the friction drive is the fact that it will not work in wet conditions. The chain drive I have not had experience wih so I really cannot speak too much about these, and the same with a belt driven set up.
What is the intended usage of your moto-bike? In other words, is this just going to be a fair weather occasional pleasure cruiser? Is this going to be used for vacationing so it~s like a mode of light use transportation around the camp site or town, is this an alternative form of commuter transportation, or is this a long distance heavy use touring bike?
Currently I am using the Island Hopper set-up and have been fairly content with it. It doesn~t quite go fast enough to suit my tastes but I~m working on that... :-}
I use my bike for commuting and long distance heavy use touring. Granted I haven~t ventured out of this city but it~s a very large city and I go everywhere, and each time I venture a little further.
I don~t know if I have been of any assistance but if you have any more questions or maybe more specific questions...
