Have any of you seen the pst on the NABD forum where they are using a push pull twist grip note left handlebar to operate a bike gearbox gear change (as old scooters)?
This is what we are going to try for Shane but just wondering about getting clutch lever to move with the twist grip same as the scooters did. Anyone know of anything that has a combined twist grip and lever?

Never even thought about doing that. The scooter I remember with this setup was in 1969 so I doubt there are many of them kicking about now, anyone know when they changed or do they still have the left twistgrip change? Was it Vespa's as well?

Just thought a bit more about this, the scooter I rode that had this setup was an Li 150(?) and if my memory serves correctly it wasn't a straight push/pull up and down but had positions for the gears. Can someone tell me if I have that wrong and a scotter setup would work for a 5 speed bike change (i.e. straight up/down returning to same position)?

im not sure about the clutch aswell but using a twin cable twist grip could do up motorbike gears as the lever returns to central position after each change, it would only require a bracket to hold the cables and somthing to attach the cables to the gear lever. its a bloody good idea that nabs |

When my brother had his first moped back in 1972,3 ....that also had a clutch and twistgrip gear selector. It was one of those bright yellow puch's,with a steel pressed frame,and a yellow and chrome tank.  |

Hold on, slow down, the push pull throttle isn't my idea or design, I saw it on the NABD forum here http://forum.disabledbiker.co.uk/viewtopic.php?t=5410 thought it a great idea and well worth a go. I know a kliktronic would be a better option but the money isnt there for one of those. Know what you are saying about cable stretch Stumpy but if we get some decent cables we should be able to minimise that (cant help thinking of those cables they used to steer that Gears of War trike). If you look at the link I have posted you will see the guy has done a few of them okay |

i converted an intruder to lambretta left bar twist gearchange and clutch lever i used 2 clutch cables and had to mess about with the length of the linkages to get it right and he said it took a bit of getting used too if i remember it cost £65 brand new from a racing scooter place at edlington near me if wanted will see if they are still going and get a number for you

Madron did the scooter gear have positions for gears or was it straight up down? Think with using it you have answered my question anyway cos it must have worked  If you have a name or number it may be helpful, we haven't started nothing yet but knowing there is a contact is always useful |

One of the early Puch mopeds (the ones that look like a bike and not a scooter ) has the twist grip gear change I had one about 25 years ago and was real fun learning to use the twist after foot change...not sure of the model but they are Yellow & chrome bikes...hope this is of some use?...Voodoo....
