Motofire,

how do you take the front fork spring out? There is a white plastic part under the fork boot, but I am not sure how to pop it out so that the fork springs are released. A step-by-step would be greatly appreciated.

Thank you.

John

I replied to your PM but I think it was lost in hyperspace...heres a step by step.

Remove fork caps,front wheel and brakes

Take forks off

Deep down in fork is a Allen button bolt

Remove this bolt(you will need a 5mm Allen head socket and an extension(s) long enough to reach this bolt)

Do this to both sides

The forks will the come apart easily

When you take them apart familiarize yourself with the orientation of the plastic pieces.

Anyone switch wheels yet? How do you get the sprocket and brake drum off??
Not on the 12...

I never took off the band brake so I cant help you there.

The sprocket comes off with a little work. The little Hex heads are thread locked on so I would suggest using some heat to break the lock. I also had to replace a few of the hex heads.

what grips are you using. something from mini 50cc mx bikes, cr 50 or the ktm's. the stock grips look shorter than big bike grips.

i went with Renthal, full diamond pattern in the soft compound. The full diamond pattern has the smallest o.d. i have seen and the soft compound is nice for little soft hands.

Y0u also need to make sure it is the road bike style and not mx style. mx style has higher "flanges", where road bike style has the smaller diameter "flanges" that are the same type as trials grips.

"Flanges" being the the end of the grip opposite of the bar end.

I cut them to length and installed bar ends.

I left the stock grips alone on the 16.0

However, on the 12.5, they are too big for my 3-year olds hands, so I cut them off and slipped in a couple of cut inner tubes from a 10-speed bicycle. This was in order to have the diameter as small as possible for their little hands.

We have gone through 2 sets of batteries on the 12.5, and one on the 16.0. Batteries last about 100 cycles, so that will tell you how durable the bikes are. The only thing that has had to be replaced have been rear tires, and a throttle. I just got four batteries for about $80 on ebay. I use the same batteries as used on the older-version 16.0 on the 12.5, they barely fit, but last longer.
