Looking for input

I dont own and have never ridden a belt drive, from what Ive read though from buku posts its a good idea to get a heavy duty wheel with these setups. The honda has alot of torque at low speed and with it in my opinion a heavy duty wheel with thicker spokes is necessary.

Have you looked at the Staton kits? They are VERY solid and offer a lifetime warranty on the gearbox. They also sell a very nice hub/wheel with dual sealed bearings. You get the hub with the kit but you have to lace it onto a rim yourself unless you buy the whole wheel setup. They have Subaru and Honda kits both. The Staton is also a true freewheel setup, it's nice for going down hills.

I have the Subaru and there's no way you're going to pull big hills and still be able to do 30 MPH, not even close.

I live in a hilly area too. The Subaru will climb moderate to medium hills with a 12 tooth counter sprocket but top speed on level ground with that sprocket is about 22 MPH and it will drop to about 11 MPH on decent hills. Steep hills need some pedal assisting, which is pretty easy with the engine power. If you have steep hills you might even need an 11 tooth sprocket which would drop to 20 MPH or so. The Subaru is a great engine, I don't think you need to worry about longivity. It is a very small engine and has limited power though. My chain saw is 48cc, the Subaru is 33.5cc. The Honda would have considerably more power but is kinda pricey.

I got my kit on ebay, they are a little cheaper and with the Bing cashback, Ebates cashback and ebay bucks I saved over $100 from the website price. Bing cashback was 12% at the time, it's 8% now and ebates is 2%.

The mount may look a little weird bit it's VERY solid and chain adjusting is super easy and fast. It helps if you have a bike with the 2 threaded holes for rack/basket mounting on both sides of the bike.

The one kit that hasn't been mentioned yet that you might want to give some serious consideration is the New in frame Kit from EZ Motorbike. You don't seem to be scared off buy spending a bit extra if it gets you the climbing ability and reliability you are looking for so this kit seems right up your alley. They seem to have solved most of the problems caused by the various reduction gearboxes out of China, and their drivetrain seems to also provide the most adaptability to alternative drives (belts) without a major increase in overall width of the motor and drive around the pedals. EZ also has a automatic drive in the works. Just to make things even more complicated you might want to also look into the Sick Bike Parts Shifter Kit for the 4-stroke motors. This system is a supplementary drive system that you add to a IF kit that moves the output of the reduction gearbox to the right side of the bike and then drives a freewheeling set of front chainrings and cranks (part of the shifter kit) and then you are able to use the gears on your bike for your final drive ratios. This type of setup may give you the best of both hill climbing and reasonable speed on the flats.

Just keep in mind that shifting after the engine is engaged makes the bike a scooter in most states and requires licensing, insurance and possibly a motorcycle license if you want to stay legal.

I would beg to differ on your opinion of the EZM...I live in a very hilly town, and pull a trailer full of granddaughters all over the place...I have done 2000+ miles since late April
I did bend my 1 piece crank for clearance, but the grubbee needs that as well, or they wouldn't include them with their kit
I have no problem pedalling the trailer with my cranks and it is not uncomfortable at all

Gearnut if you have lots of hills to climb my choice would be the titan or the honda 50cc, to me its a no brainer.

Hi GearNut,


Just wanted to make a few comments concerning the EZM kit. In stock form the EZM will out pull most and does really well on hills. The first video on you tube actually starts at the bottom of a small hill but is difficult to tell by the camera angle. My EZ proto-type will out pull a stock Whizzer on steep hills including a couple of long tall bridges in my area. The EZM, because of design transfers almost all of the power to the rear wheel, whereas other companies must pack the gearbox with heavy grease to reduce the noise. Think about it for a moment..... running gears or chain in grease reduces the power, somewhat like "paddling a boat in mud". Our drive system is one of the thinnest on the market and the total width is only 2". My proto-type is using the Whizzer wide pedal crank, and the rest of the test bikes I installed a shorter pedal crank [1" shorter] and used pedal extensions. It is important to note that most frame mounted four stroke motors will require a slightly shorter or wider pedal crank, and some are so wide [not ours] that in fact you could become "bow-legged" in a short period of time.


The new Q-Matic drive [automatic] uses an American made clutch [Max Torque] and easily climbs most hills with the stock ratios. One advantage to the EZM drives system is the ratios can easily be changed.

We designed the drive system to be easily changed for different terrain, and heavier riders. The stock automatic system has a 14.67 X 1 ratio, but can easily be changed to 16.97 X 1 in a matter of minutes. Or it can be changed to as high as 20.1 X 1 if you need to climb the side of a building. The stock 49 CC four stroke EZM motor [HS] is at home at 7500 RPMs and will deliver the following speeds....... 14.67 X 1 = 39 MPH, 16.97 X 1 = 34 MPH, 20.1 X 1 = 29 MPH.

Have fun,

Here's my crank after I heated & bent it. Works great. But I don't pedal. I only use the pedals for breaking.

Hi GearNut,

Please contact us for information concerning an Authorized dealership. We are still adding dealers and could save you money building your personal MB. Unlike most companies we don't require a large investment or massive inventory, we are far more interested in the individual and input to improve our product. For the balance of 2009 we have lowered the requirements for dealer status to ONE kit [normally 3 kits], to make it easier to join our team.

Some of our current dealers have made a business of the EZM system, while others have only become dealers to purchase kits for themselves, family & friends.

Currently some of the leading MB experts are Authorized dealers for EZM and we look forward to adding more experts, collectors, and hobbyists to our ranks in the near future.

Have fun,
