2001 SUN RETRO NEXUS 4 CRUISER

[Rat Rod]

Saw this one on the CL today at a really good price and couldn't pass it up.

The seller said he bought it new in 2001, rode it once and hung it from the ceiling. Initially I pursued it because I thought I might use the wheel set on my Klunker build, but I always find it hard to mess with bikes that are this mint and ride so good. I literally brought it home, sprayed it off with the hose and dried it off. Thought it was interesting that they incorporated the name of the hub into the name of the bike. The Nexus 4 speed hub is really nice and the bike is geared perfectly. Gotta love the 1999 Odyssey front brakes and the Joytech front hub.

Any chance u can tell me how many teeth on the crank and the wheel, that would be very helpful!

On my Schwinn Cruiser four, I thought the original gearing was too tall (the Nexus 4 is direct and 3 gears of overdrive) so I used a chain ring from a 20" Schwinn kids bike (32teeth.)

Factory:
using 46 t front sprocket (original) and 22t rear sprocket (original)
1st gear (direct) 46tooth/22tooth= 2 wheel revs per crank rev x 26"= 52 gear inches
2nd gear (1.244 overdrive) 52 gear inches x 1.244 = 65 gear inches
3rd gear (1.500 overdrive) 52 gear inches x 1.500 = 78 gear inches
4th gear (1.843 overdrive) 52 gear inches x 1.843 = 96 gear inches

Swapped out 32t chainring:
using 32 t front sprocket and 22t rear sprocket (original)
1st gear (direct) 32tooth/22tooth= 1.45 wheel revs per crank rev x 26"= 38 gear inches
2nd gear (1.244 overdrive) 38 gear inches x 1.244 = 47 gear inches
3rd gear (1.500 overdrive) 38 gear inches x 1.500 = 57 gear inches
4th gear (1.843 overdrive) 38 gear inches x 1.843 = 70 gear inches
