Replacing freewheel on Adams trail-a-bike
Spent the evening cleaning and lubing a craigslisted trail-a-bike I'd picked up last week.
The freewheel is toast and I'm wondering if anybody can help me figure out what I'm dealing with for replacement. 18 tooth, DNP, 8 splines. Photo below.
Is this just a typical BMX freewheel built into a 20" wheel? How common is that spline pattern for the removal tool (chances of an LBS having one on hand to pop it off for me)? And what am I likey to find on the hub (thread pitch/diameter) for procuring a replacement?
Doing the work myself is preferred and I've got a chain whip. Just haven't worked on BMX/single speeds before. It'd also be nice to have the new freewheel in hand before I start because, man, does my 4-year-old love riding this thing.

You can get an idea of the number and types of splined freewheel removers here. Tools, Lubes, & Cleaners - Tools - Component Specific - Freewheel and Cassette Tools - Niagara Cycle Most new bikes don't use a freewheel but have a freehub/cassette combination. Those have a locking ring on the outside of the cassette. You should have no problem finding a single speed freewheel at the larger online stores thanks to the popularity of fixie bikes. See this selection: Components - Drive Train - Freewheels - Singlsespeed - Niagara Cycle Maybe you can find an exact match.

In Bike Shop Saturated PDX bring the wheel in and ask them to use their tool to unscrew it .
Buy your own remover that matches the replacement Freewheel you will keep ..
.. tool engages the core that screws onto the hub.. a bench vise or an Adjustable wrench holds the remover .
Shimano has a 4 pin. that has 8 notches ... Maybe they engage 1/2 of them .
but Both wheel and remover Not in front of Me, 1st person, Not a Guaranteed fit thing..
