What's My Size?

Your inseam can help you find the perfect sized bike (measuring it properly is similar to pant inseams but measured a little differently). Here's how they work:

  1. Stand upright with your feet 6-8" apart.
  2. Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
  3. Compare your inseam measurement to the standover height of the bike. You should have about an inch of space between your body and the top tube.

Stylish and well engineered bike

the bike fits right in at the beach. I use it for exercise and casual riding on the flat roads and terrain at our island beach community. The single speed allows you to get your heart rate up when you want to push it.

Sweet Ride

Nice experience. Easy to navigate site and great delivery and set-up instructions. Bike rides great but I was surprised at the weight. It is heavier than I anticipated but overall a great value. If these bikes came in an aluminum alternative, it would be great!

So good it got stolen!

Loved the bike for the couple weeks I had it before someone snipped my lock and stole it. Instruction was relatively easy and the bike rode really well. If I can sum up more $ I will look to purchase again.

Mantra Single Speed.

Pretty cool bike overall. I now own 5 bikes total. There was a rattling noise coming from inside the rear double wall rim. Found a small piece of manufacturing flotsam in there and removed it through the valve stem hole. (I do all my own bike mechanic work). The Mantra comes with a 17 tooth freewheel (rear) sprocket which I changed out to a 20 tooth to better its hill climbing performance, and a higher quality chain. The rear wheel was VERY true right out of the box. The front wheel required a small tweak to get it to run true. No big deal. As an avid off-road bicyclist since 1998. I can tell you that this little road bike is a pleasure to ride once you get it set up correctly. I will simply "upgrade" parts as I wear them out over time as I do on all my bikes.... Happy with this little bike.
