It's been almost 30 years since I last drove one. Some guy here just inherited one and wants sidecar driving lessons. ? ! That's OK- I'm up for that. The thing is- I can't remember a thing about the hi-low and reverse thing. I've tried the usual BMW sites and so far all I've gotten is a little nervous pebble kicking or, "I think I hear my mother calling me..."
So- anyone know what I'm talking about? Are the 2WD Urals pretty much the same? > 4 high gears, 3 low, and 2 reverse < So- how does this all work? Any pictures?
Outch, that before was a bad help I gave you....

This now is better 4 forward/1 reverse high gear set and 3 forward/1 reverse low gear set. And the lever has only 2 positions...
The outer small tank gear lever should be the one for road/off road gearing
(with only little change for reverse too) and the one that is connected to the differential (below the seat) for reverse and/(or) differential blocking.
Excuse me for the Alzheimer effect.

Hello Uncle Ernie,
I might be completely wrong, but I "think to remember" a small (1 3/4") lever on top or back side of the final part of the gear box (between bike and sidecar) with 3 positions for to give you 3 or 4 high forward,(depending which Beemer (37 (flat head) or 750 (Over head valve)), same number low and same number reverse.
Best You google around, there are many sites for vintage bikes (obviously in German more).
Best regards
Sven
Is the bike in question a authentic R-75, a Ural or CJ with BMW badges on it or just a Ural or CJ?
There seem to be a lot of Urals and CJ's around with Beemer badges on them. Maybe more than might be expected from a survival rate of real 60+ year old Beemers. The R-75 was sort of low production in comparison with other models and there was a war on at the time so many didn't survive. It's sort of similar the machine gun mounted Steib sidecar you've come to expect. That only happened in 1942 and the decimation rate was ferocious consequently there aren't many originals still around although the car sans machine gun continued to be used after 1942 on other bikes.
The Ural foot shift pattern is one down and three up with the reverse lever on the transmission low and on the right side at the rear of the motor.
