EPA certified? as what? a pollution spewing P.O.S.?
vegetation said: Anyone know if this motor will be able to power up paved 12%+ grades?W/ ~5hp it should be able to take 12% at at least ~20mph, but if it doesn't there seem to be small sprockets (36t) available that should do the trick.
Totally off-subject, and braving the red; hoping for someone kind enough to either provide the answer, or point me to it.
The left pedal of my nephew's new K2 bike has come off. The threads in the arm(?) are completely gone. How can it be fixed? What parts/tools are needed, and where to get them?
I am asking because his single-parent already over-spent on a "better" bike which he could use as transportation to high-school. The first day, he had a flat, and had to bring it to the shop for a new tube. Cost, including labor: $18. Two days later, the other tube. Cost: another $18. Before the week was up, he lost the pedal. Probably wasn't threaded right in the first place. Really can't afford the shop this time.
I am handy with tools and projects I am familiar with. Bikes are not among them; but I am confident that I can manage this. All I need is one kind soul to guide me. TIA.

If the threads in the pedal cranks are shot it more than likely happened due to an incorrectly tightened pedal and will need replaced.
There are many types of pedal crank, S-shaped (one piece - usually cheap quality) and 3 piece (can be good quality) which bolt on and even the type where the cranks bolt on using cotter pins (usually cheap quality).
You might be able to find what you want with further searches but the repairs you need to do are fairly simple really.
A puncture repair should only cost the price of the new tube (if you can't use a puncture repair kit) and 5 minutes of your own time to replace when you know what you are doing (From a labour cost point of view shops won't normally repair a punctured inner tube as it would cost more than giving you a new one.)

The kit I put on my bike is pretty similar. Makes the bike harder to ride when you are not using the motor, but otherwise, pretty fun to ride. I really thought I would ride it everyday to work, but it's more of a novelty.
I'm in Bay Area, and plenty of people do it here, myself included. It's kind of in a gray area for CA. Even though it's a motorized bicycle, I got a license plate for it from the DMV. You also need a motorcycle license, plus ride with a motorcycle (DOT approved) helmet. Oh, lights, mirrors, etc. I've built mine last 4th of July, and I'm still on my first tank of gas since I don't ride it too often.
It does make the bike very hard to ride if the motor isn't running, but it's a cheap alternative to getting a scooter/motorcycle.
D'oh, just found out that any motorized 2-3 wheel vehicle(engine size doesn't matter) requires a Motorcycle endorsement, registration and insurance. LOL, woops. Will still be a fun project though.

One thing about repair kits- I suggest *not* using the scratchy metal clip that comes with many kits. This is supposed to clean the rubber, but ends up shallow cutting the tube, big enough that air bubbles thru them underneath the patch. Sandpaper is a lot better to avoid this problem.

I just looked up K2 ,, pricey bikes! ,, if it was bought at a bike shop they usually warrant for defects and if the pedal/crank threads were bad then that's a warranty issue .. most japanese/chinese bikes use a smaller metric thread for the pedals and the US made Schwinns (not the new ones ,, schwinns name was sold to the Chinese) used a slightly larger attachment for the pedal (SAE) ,, you could always remove the crank arm and drill/tap it for Schwinn sized pedals. remember the left pedal is always reverse threaded so it won't come loose in normal riding,, lefty-tighty ,, righty-loosey. you could also just try cleaning up the threads as best you can and hit it with some blue or red loctite.
The other poster is right ,, inner tubes are about $2.50 ==> $3 and can be changed in minutes (an expensive bike like this should always have quick release wheels) , you shouldn't have been charged for changing them , the kid should be given a pair of new inner tubes from WalMart and you show him how to change them ( remember NO TOOLS.. EVER!! you will pinch/cut the tube ) ,, he can then keep his current tubes for future flats ... he will be much more careful about riding in thorny areas and bashing into curbs after that..
You can always put "thorn proof" tubes into the tires or a hard plastic "thorn proof" liner to prevent flats.

I've checked Craigslist and I think there's a place in Santa Cruz that does it for ~$200 or something... I haven't seen anyone else doing it closer to SF.
Friggin pedal fell off my mountain bike too .... mine is a WalMart cheapo tho.

The pedals on a bike are both right and left hand threads. Probably put the wrong pedal on the wrong side. Some bike shops can try to re-thread the crank. If not, a new crank.

I just FORCED the pedal back in. Im pretty sure it will never come out again.

Your going to want to buy and install plastic inner tube liners. This will provide an extra barrier of protection against thorns or anything else causing flats. I've seen them at WalMart for about $10 for the pair. Here's a link to what I'm talking about:
Above linkified .. i had a slime tube and i have no idea what happened but next time i get on my bike its flat ... the tube is split with green goo everywhere ... i do think the above might have helped me tho when i first had to replace the tube ....
