That's actually a great point that I hadn't thought about and should have probably checked before buying a Helix. My Tern Verge's seat and handle bars feel pretty close together. Although I'm not massive, at 183cm I'm reasonably tall, and have to have my seat at max height to avoid knee discomfort on longer rides. Mostly the ride is comfortable, but on any kind of steep hill (anything over 10% grade I think) I have to lean forward right over the handlebars to keep stable and avoid accidental wheelies. It's not helped by often having a backpack full of crap with me on long rides. God, I hope the Helix is better than the Verge in that regard, though thankfully most roads around here are not 10% or more
