Also be aware that Sinner Bikes is completely hopeless at marketing, which means they have a host of extra cool options that they do not publicise.
Key example is their new air /oil dampened rear shock absorber which performs much better than the original and is better and way cheaper than after market versions which the rest of the velomobile community is buying and retrofitting to their quests and mango etc. I got this and recommend it
I also got dual LED indicators (free option) and dual LED rear light (small charge - maybe 20 euro or something) which are good if you do night commuting. I know you used to do a lot of commuting miles so worth considering.
As another example of their covert marketing expertise, heres a link to some hidden pages on their website which show photos of previous customer bikes. There are mangos there fitted with also sorts of options (such as Di2 shifting, carbon fibre bodies etc) that are never even mentioned as options anywhere on the site.

Fear not though, they make an excellent product and they have made some recent changes in personnel to address their prior customer service / communication issues. Harma & Harry are now delighting customers globally !!!
