As mentioned om the Tandems board, I've just bough a Longstaff tandem trike. I've a few questions which are trike, rather than tandem, related so I've put them here.
The serial number stamped on the rear BB shell ends in -88, so I'm guessing it was made in 1988.
It's got a two wheel drive with a six speed block.
A bit of web based research turned up this post
https://yacf.co.uk/forum/index.php?topic=18038.0 which suggests the grease nipple isn't particularly useful and that a Trykit conversion is better than the Longstaff 2WD transmission. I can't find anything about what maintenance, if any, is needed for the 2WD unit nor how they work. Pointers would be useful.
It's got a rear carrier bolted to it.
At present I bungee a small rucsac to it to carry waterproofs, tools,
fags etc. Is there a neater solution? There is a pair of M10 bolts on the left and right sides , facing outwards (see photo). What are they for? There's also a pair of M5 hex head socket bolts facing downwards on the carrier cross member. Again, what are they for? Light fixing?
Finally, what bodges are available for fitting rear mudguards. As you can see it's got rear hub brakes. I'm thinking of attaching something to there.
