I look forward reading to Chris’s reply to you.
Like you, I have been on the fence about folding bikes. The most extreme folding bike is the Brompton, and the electric version will go on sale soon in the US. That compact fold is very attractive. But much about the ride is compromised for its ultimate folding ability, and the electric means significantly more weight. The opposite extreme is a full-sized ebike, but racks to haul them require a trailer hitch due to their weight, and there are other portability disadvantages. I’m thinking now that the Tinker is just about the ideal compromise. Superb ride, and while not folding it is still compact enough with handlebars down to haul inside any vehicle. We are actually considering 2, and hauling 2 inside a hatchback seems no problem. Removable pedals will help. Removing battery & seat post lightens the weight. Removing the front wheel might also help, but I was advised that could cause problems and be less balanced to maneuver when lifting. I found the Tinker light enough to manage with the front wheel left on.
We test rode the Tinker HS against the Vektron S10. The ride was comparable, of course with the exception of the Tinker HS higher max speed. I found the gear shifting to be clunkier on the Vektron. But finally, the ease of lifting and storing the Tinker in a hatchback (battery & seat post removed), pretty much canceled our need to fold. We are sold on the Tinker when it comes time to buy.
