3) Install 2x washers against the sprocket
4) Install Securing nut firmly. May require a tap with a screw driver and hammer.
5) Install Bearing against the securing nut (Notice position of the bearing).
6) Apply grease to the bearing and the seat surface inside the bottom tube.
7) Install crank arm through the frame of the bike ensuring the bearing is sitting in the seat.
8) Apply grease to 2nd bearing and seat then insert the bearing over crank.
9) Install locking nut firmly against bearing
10) Install washer onto crank arm. Notice washer has a key in it to secure against the locking nut this helps to stop the crank coming loose.
11) Final step install the 32MM Nut firmly against the washer.

My 4 year old is stoked with his new "Big kids Trick BMX".. I was looking for a bike he can go from the skate park to the race track and stumbled across wildcat bikes! I ordered this the week before Christmas and the team went above and beyond to get it to us in time. Not only is the product of exceptional quality but the team behind it all implement the same standards with their customer service. Thanks again guys!
My son is absolutely in love with his bmx. I do look forward to ordering again soon.
We ordered the new pedals for a child's bike my partner was doing up. They were a great fit and colour.
They arrived very promptly.
My son is absolutely made up with this mini bmx bike he is literally riding from waking up until it goes dark outside. Rides to and from school and takes it in the car to ride while his sisters do their swimming lessons.
It arrived in no time, easy to assemble with provided instructions and that smile on his face was the best!!!
Thank you wildcat for this awesome bike I have one very happy little Boy!
Highly recommend:)
