Question: Does it need to be assembled?
Document: The trike came earlier than expected. It came almost fully assembled and in very good condition. It's a fun ride, and gives me and my dog lots of exercise together. I like the nexus hub, and finally conquered a hill on my road.
I've had my Rover 8 for about a week now and I love it. I'm disabled (back injury) so I can't ride a regular bike, but I have no problem riding my Terratrike. I only ride on the concrete in my neighborhood. It's enough for me to get much needed exercise. Lydia at terratrike answered all of my questions. The trike is shipped to you completely assembled and adjusted for you. And all of the extras that I ordered were installed for me.
My wife and I have had our Rovers for something over a year and a half now. We love them. I'm 6'4&#34; and she is 5'3&#34;, and yes they are adjustable for both our heights, however, since the length must be changed, the chain does need to adjusted by taking out or putting in some links. I carry a &#34;chain breaker&#34; and 6 or seven links with us when we ride.
We bought 2 rover 8 trikes to use at our summerHome in Jackson  .they are not as satisfactory as our Path Touring model in Florida. sprocket is designed too small for efficiencyHad to replace rear tire with knobby tireShipping from mich was ok
The Rover is geared pretty low and I'm usually travelling 10-12 MPH with it, and that's okay. I'm mostly enjoying the exercise. The fastest I can peddle gets me to about 16 MPG and the 8 gears allows me to climb some fairly steep inclines with ease.
Lots of good options and much fun.
Little worried about buying on line.trike came in perfect condition.factory contacted me for correct sizing and color took out of box and road till dark also shipper did great called and was on time.very happy with product and purchase
If you have any back issues, check with your doctor but I think you would be able to ride a Rover. Easy to get on and off. It is a great trike.
I wear an AFO brace on my left leg due to rheumatoid arthritis. I bought a special heel-backed pedal for that left foot & I'm a wiz on the trails! I enjoy the fact that the bike is a smooth ride. Easy to steer, never feels like I will roll over. I'm free as a bird on my bike!
I needed a replacement for my 40-year-old 10-speed which I haven't ridden for a while. Wanting to cycle again, and being quite overweight, I wasn't looking forward to climbing on top of the skinny little bike seat. Then I found the TerraTrike Rover, watched all the videos of real folks really enjoying it, and thought this might work. Since it was delivered, I've tried to spend every possible moment on the bike.
Answer: yes
