The Turbo Vado SL rides and pedals just fine with the motor off, no motor drag. I'll never get stranded with mine, because with the motor off, it's just a mid-30 pound hybrid road bike, except it rides and pedals much nicer than any other non-motorized mid-30 pound hybrid, because it has nicer components. I've ridden for miles on rolling flats, and even gentle uphill without the motor. In fact, when I first got it, I did that a lot, turning the motor off when I crested a hill or was riding on rolling flats, thinking that was better cycling than keeping it on--I got over that really quickly. It's just so darn much fun to ride with the motor engaged, even on Level 1, that I now cannot come up with any legitimate reason to ride it without the motor engaged in at least ECO Level 1 for any distance. Who doesn't want to go twice as fast for the same energy output? I've never ridden my Vado SL up any really steep hills without power (because why on earth would I want to do that?
, but it would do it. The Vado SL is much lighter than an old Schwinn Continental and loads lighter than a Schwinn Varsity--both of which bikes have been pedaled up miles and miles of steep hills all across the country.
This past weekend, my buddy's Trek Verve ran out of battery power about 7 miles short of our destination. End of bike trip for us. His bike is so heavy, that he doesn't even try to ride it without power, unless it's downhill or flat.
