WTD. Lambretta gear shift!!
I've been asked to help convert a 900 Diversion trike for a paraplegic bloke to use. Most of the bits are sorted but the gear change still needs
resolving. I've started to build an electric shift using a couple of central locking servos but then I had one of those lightbulb moments!
Lambrettas use a twisty handlebar thing for the clutch lever and gearchange so I want to try the same. Money is very tight for this job so I'm
looking for a cheap assembly that I can adapt to fit.
If anyone has any bits kicking about, shout up. Or, if you can think of another way to get round this problem, lets hear it.
TIA.

I don't want to rain on the idea, but the Lambo handlebar shift extends into the headlight section, the quadrant which the cables connect to is
under the headlamp cover, and the cables run down the steering shaft...
THIS Might do the trick for you??

Also if you are talking Lambretta parts they are not cheap.

Many many years ago I had a Vespa. It was a '56, prior to the faired in handlebars and had a very simple device with external cables to change
gear. From memory it was a quadrant about 3 to 4 inches in diameter that pulled either cable. I think you could manufacture that from scratch without
too much difficulty.
I also think that the old British invalid cars of the 50s had a similar handlebar change arrangement.

Cheers guys and you're right about the suitability and price of the scooter parts!!
I like the hand shift you've linked to Pete so I'll see if there's enough cash in the kitty to buy it. The main problem is the trike
has been borrowed and is to be used for just one trip round Ireland and the chap involved doesn't have much spare cash! I'll have another
look at using a throttle push/pull twist grip and see if he can work the clutch at the same time, and also continue to work on the central locking
servos. I have a nutty idea that the horn-push can be used to change up, unless the brake lights are on, in which case the horn button will actuate
the down-shift solenoid. It'll mean the guy will have to stroke the brake lever when changing down going uphill but I'm sure it's
doable!
