Would you believe I'm planning my next build? (4 Stroke Content)

http://www.bicycledesigner.com/defaulthome.asp?Main=/partsmain.asp%3FType%3DbrakeThere is a way to mount caliper brakes to that spinger. I've seen kits for the 20", but havent found one that says 26" yet. If you look at the "red barron" thread in the picture gallery, it has one. No fenders on that one thou. I've seen stretches with over fender brakes, just havent found them yet. My dyno has the same style fork.

edit: It just struck me that if the kit adds something to bolt the brake to... one size fits all?

yup, there it is, thanks for the correction :)

but i have to wonder if that geometry will actually work? doesn't the relative position of brake-to-rim change with each bump?
 
Nope the whole fork pivots. After lookin at it a bit, not sure I'd trust it at speed. lol.

edit: Please do. I'd be interested in hearing(er reading) what his experince has been with them.

From redb66:

It should mount up just fine. You may have to leave off the fender. The springer front end has a pre-drilled hole in the correct location.

It works just fine on my bike. The idea behind the springer front end is to put the tire (point of impact...bump in road) out in front of the head tube to help dampen the shock. The brake itself, when applied has a forward movement as it grips the tire. I suppose is you were on really rough terrain and applied the brake it may change the relative position. The springer front end is pretty firm and can be adjusted to different stiffness settings. I have the dual pull brake lever with the same type of brake on the rear tire. So far so good. Overall ride of the bike is excellent. With the dual spring seat and the springer front-end it is a very comfortable ride.


Nice. Looks like I'm going for that bike.
 
More research tonight, this time on engine kits.

I have three options, I will put them in the order of most likely to least likely (which is mostly dictated by funds).

1. JL Hoot kit. Has the same engine as the bird dog kit but contains what most people call an "inferior" gearbox. The reason this kit is most likely to be the one is the fact that it's so cheap. I know that traditionally "you get what you pay for" but this will give me plenty of tinker time as well. It also doesn't come with a killswitch (which is fine, I'll wire my own and use it as an anti-theft device), and comes with a non-adjusting mount and a different crank set. I can fix the mount issue and devise my own way to get the mount on (I'm an industrial designer, it's what I do). But the crank set might be a whole different can of worms. Will it fit on the Micargi that I posted earlier? Or does the one piece crank foul everything up?

2. Bird Dog kit. The obvious advantages are the adjustable mount, the better gearbox, and the twist throttle, kill switch, double brake lever combo. Idealistically, this is the way I'd go, but realistically, I can't afford it.

3. Same as the above kit with a real Honda engine. It'd cost 60 or so dollars more for a real honda engine, if I hit the lotto maybe I'll do this.

So in conclusion, my questions regarding the JL Hoot kit are: Is the gearbox entirely worthless/what grease do I pack it with? Will the crank set fit my above posted bike?

Here's an except from a post where BirdDog crucified the first the JL Hoot kit. I placed commentary in parenthesis beside each.

1) The gear box included in this kit is NOT the same as the Grubee gear box. Grubee actually has a patent on his design. The HuaSheng engine output shaft is too short for this gear box clutch design. This means that you have to use several flat washers to make the shaft longer. This is causing the bell housing to split and fail after a short amount of use. (A definite concern, true or false? Can it be fixed?)
2) The gearbox is not compatible with the Honda GXH 50. (A non-issue, the engine is going to he a Chinese copy anyway)
3) The gearbox does not include an engager system. (Not entirely sure what this means)
4) The gearbox includes a fixed rather than a freewheel output sprocket. (Not entirely sure what this means)
5) The kits are sold with no warranty from the factory. This means it is up to the vendor to stand behind their product. I tried to follow the instructions to submit a warranty issue with one of the vendors and the web form I was supposed to use did not exist. (I figure I can fix it unless the engine totally ruins itself. I don't expect great support for these kits anyway, it's more of a self-reliant hobby)
6) To my knowledge there is currently no way to obtain parts for this kit. If you break something I guess you’ll need to buy a whole new kit. (This doesn't make a ton of sense to me, if the engine is the same then why not just order parts from Bicycle-Engines for it? Did they do something I'm not aware of to the Bird Dog kits that makes parts incompatible?)
7) The mounting plate is not adjustable which limits the bikes the kit will fit. (A non-issue, I can figure this out)
8) Does not include the dual brake, throttle, kill switch grip. (Non-issue, I can get an aftermarket dual brake)
9) Does not include a kill switch. You must purchase and install your own. (Non issue, I can install a quality switch in an inconspicuous place and use it as an anti-theft device)

That's all for tonight.

Take care everybody. Thanks for the assistance.

Sheik, I'll take a stab at your questions as best I can:

1) The gear box included in this kit is NOT the same as the Grubee gear box. Grubee actually has a patent on his design.

[A patent has nothing to do with quality]

The HuaSheng engine output shaft is too short for this gear box clutch design. This means that you have to use several flat washers to make the shaft longer. This is causing the bell housing to split and fail after a short amount of use. (A definite concern, true or false? Can it be fixed?)

[Don't know]

2) The gearbox is not compatible with the Honda GXH 50. (A non-issue, the engine is going to he a Chinese copy anyway)

3) The gearbox does not include an engager system. (Not entirely sure what this means)

[The Grubee kit has a lever that allows you to disengage the gearbox entirely so that you are not turning the gears when pedaling without the engine on..or even with the engine on, but not "engaged"- how important? How much are you going to pedal alone? If very much, this is important, if not, it is less important]

4) The gearbox includes a fixed rather than a freewheel output sprocket. (Not entirely sure what this means)

[The small sprocket that transmits the engine power to the rear wheel sprocket from the engine freewheels when the engine is not engaged, that is, it spins freely and does not turn the gears in the gearbox- importance is the same as #3]

5) The kits are sold with no warranty from the factory. This means it is up to the vendor to stand behind their product. I tried to follow the instructions to submit a warranty issue with one of the vendors and the web form I was supposed to use did not exist. (I figure I can fix it unless the engine totally ruins itself. I don't expect great support for these kits anyway, it's more of a self-reliant hobby)

[I think you are right about this- it is a self-reliant hobby full of tinkerers]

6) To my knowledge there is currently no way to obtain parts for this kit. If you break something I guess you’ll need to buy a whole new kit. (This doesn't make a ton of sense to me, if the engine is the same then why not just order parts from Bicycle-Engines for it? Did they do something I'm not aware of to the Bird Dog kits that makes parts incompatible?)

[I think he is talking mainly about the gearbox itself and since I don't know how reliable it is, I don't know how much of a concern this is]

7) The mounting plate is not adjustable which limits the bikes the kit will fit. (A non-issue, I can figure this out)

[It may be a non-ssue, but I would spend some time getting measurements to make sure it will work with the bike you plan on using it with before you order- this can be a big issue. The engine weighs 12 pounds and will vibrate- the mount needs to be solid]

8) Does not include the dual brake, throttle, kill switch grip. (Non-issue, I can get an aftermarket dual brake)

9) Does not include a kill switch. You must purchase and install your own. (Non issue, I can install a quality switch in an inconspicuous place and use it as an anti-theft device)

The difference in price is about $80- is it worth it? To me, yes, but that doesn't mean it is or should be for you. When I did my research, I found there was more information out there about the Grubee kit and I needed the adjustable mounting plate as well. Also, I think a one piece crank may be optional with the JL Hoot, but I have only seen it listed with the 3 piece and I needed the 1 piece. I am happy with my Grubee, but that does not mean the Hoot will not work for you. Keep in mind the $80 you save won't mean much if you have to fab stuff up, make stuff work and replace kit parts- Good luck!
 
Fantastic, HoughMade. I'm going to do my best to make this a pretty definitive thread for people doing 4 stroke on a budget.

Now I'm having a problem deciding. I'm going to be riding this around campus, it's going to be my only real form of transportation, so I want pedaling like a regular bicycle to be an option. Now, I've heard of people able to get the price of the JL Hoot kit down to something like 220 or so shipped...which really makes the kit tempting. I have access to a pretty full fledged wood/metal shop, I know I could devise a mount, I'm pretty crafty.

I also have to get a double brake lever regardless for my bike, which comes in the Whopper Stopper kit. I should probably just break down and get it, but it pushes my budget pretty far. Does anybody know how much Bicycle-Engines charges for shipping?

You're probably right. I'll probably cough up the extra dough. I might have to cheap out on the bike a bit.
