Great RV Bike and Nice Nemo

Great for RV life! Love the ease of folding which allows us to put in back of the truck as opposed to having a bike rack on the rear of the RV. Took about 45 minutes to assemble.
I must say their customer service is prompt, professional, and helpful.

Just over overall cool product

I think for what it is, it's one of the coolest things I've ever bought. it's versatile and can do the distance but honestly really shines the most as a super-versatile bike that can deal with heavy city traffic. I live in a congested traffic city and this is really the perfect option for any big event that requires heavy parking fees and/or totally gridlocked traffic. I often park a reasonable distance away and just take a short bike ride into events. it's also small enough that if you want to pop up on a sidewalk to avoid idiot American drivers who still somehow have a fast and furious mentality, regardless of human life around them, you can do so without really pissing anyone off because it honestly just looks like a cool BMX bike.. (somehow no one cares what skaters do lol) The battery life is solid. I took it to workout and get groceries - about 6 miles in all and then all the way downtown to work and back (and my coworkers couldn't stop joyriding it during my time there).. so yeah about 13 miles in all give or take depending on alt routes and extra bs I prob did.

My Dolphin

The bike came earlier than expected, how great was that! Assembly was very easy and it was up and ready to ride in about 10 minutes. The bike took no time to get used to and I'm riding it 3 times a week to my gym. I live in Brooklyn-NY where it's very difficult a car, so I use the bike for local errands. It's great.
