Buyer Aware

[LesIzzMoore]

Thanks for having this site. I am looking for the best motor to install on my Schwinn mountain bike in Massachusetts. I know people have probably learned a lot the hard way, so I'm hoping their help might save me that way. I'm basically looking for the quietest motor at 25-30mph that I can install like a rear luggage rack. I like the looks of this one and the Mongoose is similar to the shocks on my Schwinn: http://www.bikemotor.com/images/mongoose xr200.JPG

Thanks Again,

Nate

Hey Nate,

A 1.6hp Robin/Subaru engine with this kit would be more than enough to fill your needs.

2 or 4 stroke?..............or go radical & use a post hole driller.

Thanks

I appreciate the helpful responses! Any links? All I care about is noise at cruising speed.

From what I have read the 4 strokers are quiet. Also I have noticed that the prices went crazy low for motorization. Either way I think you cant go wrong. Might consider the type and style for future "other bikes" in case you ever decide to get a different bike.

Look through their Engine Info & see what u think.Your probably better-off with a 4-stroke but the 2's are also VERY good.....it's all personal preference.
See also the Engines/setups at Staton.

The Robin/Subaru 35 not only IS quiet, but I think can be even muffled more based on some of the experimental threads done here.

As to speed, following the break-in procedures at the beginning, (basically changing oil a couple of times, using a good synthetic like Mobil 1), on the GEBE you can increase the mph by 2-3 when you've gotten about 500 miles on the unit, by changing the drive gear from "normal" to "highway".

I'm about 175lbs, have one on my recumbent, and it is doing about 26 mph pretty easily, with about 300 miles/2 oil changes so far. I'm trying to get to the 500 miles ridden mark by the middle of March, so I can make the drive gear switch.

fetor56, I looked at that link. Interesting notion, especially if the gearbox can be rotated through 90 degrees to run the output parallel to the ground. That engine is set up to run upright - it wouldn't like being laid on its side. At the rated output of 150 rpm, assuming a drive gear and driven sprocket on the wheel of the same size, you are looking at about 12 mph. Go with an output sprocket twice the size of the wheel sprocket, and 24/25 mph is readily doable.

Now picture this - go kart differential set up so the input shaft is vertical and driven by the output of the posthole digger - engine is horizontal, both rear wheels of a trike are powered, and the whole thing is quite low behind the seat.

Sound

Hey Nate,

I found a video with good sound of the motor at the end of the video. Is this really the quietest?
