The fit is a little rough for me. I'm tall, about 73 inches, and I feel like the bike is small. I've ridden a few dozen miles to include a trip with a kids trailer towed behind, and it hasn't been really uncomfortable, but a little cramped compared to my Schwinn Trailway 28"/700c hybrid bike. Seat adjusts up but feels tilted back a little more than I would like. I have ridden in shorts and tshirt to the beach as well as khakis and a button up with backpack to work, ok comfort both ways. Perhaps it will just take some time to get used to.
I have had my new e bike for about 5 weeks now and covered over 500 miles, it has been an absolute joy - you still get plenty of exercise but in a much more pleasant way than with an ordinary bike, it takes hills in its stride and the ride is very stable and inspires confidence even over rough country roads, the front suspension helps a lot in this respect also the bike is equipped with dual disk brakes. I have fitted mudguards back and front - I had to modify the stays on the front ones by making a right angle bend in them so that they could be attached to the forks, it has proved well worthwhile fitting the mudguards. I have used all assist levels and you can always step to a higher level if the need arises. I can highly recommend this bike and it is my opinion that it would be difficult to find a better e bike for the money - many more expensive machines offer less specification!
