ICE, europas kanske mest kända tadpole-tillverkare har en del åsikter kring Rohloff vilka sammantaget ger att de INTE rekomenderar växeln till sina kunder.
Allt är inte direkt överförbart på en tvåhjult liggcykel. Framförallt är man intresserad av större växelomfång och lägre lägsta-växlar på en trike (så låga att man cyklar i en hastighet under balanshastigheten för en tvåhjuling).

"Fitting a Rohloff rear hub gear to a standard model Trice such as the Q
ICE do not offer the Rohloff hub as a factory direct option however, your dealer may be able to fit one to your trike. Below is some information which should help explain our thinking on the hub and details most of the parts you would need.
What we don't like:- 1. You need a rear chain tensioner because of the way the chain line works on a Trice and also if you want to run a front derailleur.
2. You need some device to keep the chain on the front chain ring if you run a single ring, otherwise the chain can jump off.
3. If you run a Rohloff with these devices then it comes with a weight penalty against conventional derailleurs.
4. The Rohloff can be noisy in some of the gears.
5. The hub feels like it has more internal resistance than a conventional derailleur system especially in some gears.
6. The shifter needs to be mounted "upside down" with the cables sticking out in the air above the grip and the brake lever or else it is too hard to grip and shift effectively.
7. With a single front chain ring of 52T and a Rohloff 16T sprocket you get a gear range of approx 17.7" to 93" on a 20" wheel - not really low enough for big hills and not really high enough either. So better to run at least a double front of 39/55 then you get a 14" low which is pretty good for big climbs and touring loads. The top would be 98.3" which is OK. A 15T Rohloff sprocket is available and that would give you 15" - 110" with a 39/55 front double. If you run the Rohloff with a 15T and the standard Campag Veloche triple which the Trice standard models come with then you will get a gear range from 11.4" to 104". That's probably rather too low realistically - you just don't need it. The 104" is fine. ALSO, NOTE THAT THIS GEAR ARRANGEMENT WILL INVALIDATE THE ROHLOFF GUARANTEE BECAUSE THE LOW GEAR EXCEEDES THEIR MINIMUM OF APPROX 14". RUNNING THIS KIND OF LOW GEAR IS ENTIRELY AT THE CUSTOMERS OWN RISK.
8. Our standard model trikes such as the Trice QNT are designed and built to have a NON dished rear wheel allowing for greater tyre clearance to the chain when big tyres are used and a stronger wheel. The Rohloff Hub is designed to be built up as a non dished wheel in a conventional bicycle due the flange positions. However, the Rohloff must be dished on our standard models if you wish to run with maximum size tyres (hence making the Rohloff build up slightly weaker).
9. The Cost!
What we do like.
1. Shift to any of the 14 hub gears whilst at a standstill.
2. Nicely made and looks cool.
3. Interesting talking point (especially if you like talking gear ratios)."
