I am considering purchasing a motor for my bicycle. After lurking here for a while, I have decided that the wizard 4- stroke would suit my needs best. I have a few questions before I purchase, though.

1: What are the dimensions of this engine? I need to know if it will fit on my bike.

2: Is this engine any good? If I must use a different kind, my budget is 350 total and I prefer a 4 stroke.

3: How much weight can this push? I weigh about 200, and I will have a (25lbs at most) pack for getting back and forth to work.

4: My work involves multiple 6 mile or shorter trips during the day. Will I overtax or strees the engine? Standard southern climate.

5: Have there been any problems with the seller at that website?

6: Will my bike handle it? Here are the dimensions.

It is a 21 Speed "Pacific Vortex Aluminum 3.1 Elite" Mountain bike. The vertical bar under the seat measures 15", inside the triangle. The Horizontal bar is 2", again inside the triangle. The diagonal bar measures 24".

There is no shock on the frame, nor near the rear wheel.

Tires have a 22.5" rim, with 36 spokes. With the rubber on, they are 26".

It has front and rear wheel hand brakes.

Umm.. there is a kickstand? ;)

Thank you in advance for your help.

I am wanting to see what shows up with your thread here -- new myself.. That Wizard engine shown -- says it's 49.1cc -- rated 2hp at 6,800rpm.. I am NOT THE EXPERT HERE -- but I am thinking that a 49.1cc motor would be more than 2hp.. Am I wrong ? I have a 33.5cc rated at 1.6hp... I'll probably get blasted for this remark or question - but - is the Wizard made in China ? If so I would want to pay extra so as to buy something made in Japan.. My buddy a while back had a motor from China installed on his bike -- 50 miles later - no spark... Happy Riding from - Mountainman

One of my buddies has this same kit. I'll answer as best as I can.
Question #1 I don't know the exact dimentions but it is a little bit wider than the two-stroke kits.

#2 My buddie hasn't had any complaints about the engine. And from what I can tell, it is a clone of a honda. And the only other kit that I know about that is a 4-stroke is Dax's titan. (thatsdax.com)

#3 My friend weighs around 220. But we live in FL (no hills). And the motor can handle it, at the most, you might have to help it by pedalling a little bit.

#4 It should be able to handle it if it is anything like a honda.

#5 My friend got his kit about when he imagined he would, there were no big delays in responses or communication that he talked about.

#6 I would have to see a picture of your bike. (My spatial thinking isn't very good)

p.s. Why do you prefer a 4-stroke? (2-strokes don't have to be the nasty-dirty smoke shooting stereotype that everyone assumes that they are)
They can be clean too. and they cost less and they look cooler (in my opinion)

That thread refers to a Honda Gxh50. The wizard site made no mention of the manufacturer of the engine.

So, if they are similar engines, what I am after is this:
Depth (Less Shaft): 7.7"
Width: 10.8"
Shipping Weight: 20 Pounds

So, it is roughly 8x11" so if I can place an unbent piece of paper in there the engine should also fit.

#6I was unable to find a picture online, so I'll need some time to find my camera.

I selected a 4 stroke based on this quote in the "noob thread" here.
On the other hand, 4-strokes make a pretty efficient motored bike due to their complexity. They get better gas mileage, more torque, & not only do they emit less noise into your surrounding, but also less pollution. Due to the nature of 4-cycle engines, you must change the oil. You might even need to do some valve adjustments. All of this leads to a generally more reliable system than a 2-cycle.
This is pretty much why. I am also not fond of mixing oil and gas. I have must spill stuff fingers.

I am not dead set on the particular brand of engine, so long as it is a 4 stroke and less than $350 after shipping. I also prefer to avoid a chinese built clone. So if someone has a recommendation, let me know.

If you are willing to spend the extra money, the titan is worth it. (I'm sure others will back me up on that).

trying to help, read the thread.

the topic i referred you to is an in-depth discussion & comparison of all the above mentioned engines, including the info (or lack of) that's available on each of them, and why it may or may not be available. it might prove helpful in your quest.

I have gone through it, and it was helpful. However, I am undecided on my engine now.

If anybody can point out for me a 4 cyl engine that does 30 mph (200 lbs rider + 30 lbs equipment), costs < 350 shipping included,and is not made in china, I will buy it today.

If there is a 2cyl that fits these specifications and can handle a 50 mile nonstop trip, I'll consider it as well.

Thank you all.
