Strida folder
People love to innovate and create, especially in fields where a standard solution has not evolved yet. Before the era of the Brompton, that was the case for folding bikes. (see post #11 for the Brompton) Achieving the goal of getting the bike to quickly fold up to a suitably small size does come at a cost, and the trick is getting the trade-offs and compromises right. The Strida folder bike may have prioritized folding to a small size a bit too much.
