Haha yeah I saw your reply on email before the edit and I was going to update you on that. I expect the SR to arrive within 2 to 4 weeks - likely early to mid August.

There's a pretty comprehensive video review by electricbikereview.com that goes into detail and demonstrates what it's all about.

ShareRoller Version 1 Review

It's definitely noisier than I imagine but the sheer versatility of such a device sold me from day one. Everyone is saying it is expensive, which is true because it's being manufactured in relatively small numbers. However, the Brompton setup is very well thought out and takes care of any remaining doubts I had.

Like you, I intend to use the ShareRoller as an energy-saver for climbing, and hot days (of which there are plenty in Singapore) - the bulk of usage will likely be from my wife who simply loves the idea.
