How to measure my inseam for a bike

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.

    All of my friends now want this E-Bike

    This E-Bike surpassed even my highest expectations! I love taking this out to run errands adding a little more fun to a regular day. People are constantly asking to ride it when they come over and I’ve even gotten a few friends to buy one now. The color, tires and smooth ride make all the difference. What’s not to love?!

    I'm a fan

    The Rev+ rides great and has plenty of power for my usage. I typically pedal all the time so the range is seemingly infinite, I had to actually try to get the battery down. I'll be putting plenty of miles on it.

    I like having both the throttle and the pedal assist, it comes in handy for slow obstacles where pedaling might be hazardous. It's also nice to get it going after stopping without needing to drop gears.

    The assembly instructions could be better, but it's easy enough to figure out.

    Fat Tire Fun Half the Effort

    The Koa Rev+ is a beast! As a road bike it navigates like an 80s Cadillac. Off road it is going to take some getting used to. I took it into the canyons near my house and I wasn’t prepared for all that power. I quickly realized I could just leave the pedal assist at level 1 since all you really need off road is a little helpful nudge every now and then. I ended up walking it over all the water crossings as to not end up in the drink. Climbing hills however was an absolute joy. The 2 second delay before the juice kicks in feels a bit delayed on the road but welcomed off road. I feel like I just need more trail time with it before I feel fully confident. I rode off-road for an hour and it still says the battery is full! Super happy with it and I can’t wait to log mor trail time!

    Style, performance

    This is my second Koa and I love the quality of the bike - it feels incredibly sturdy and well-made. The battery life is impressive, too. I've taken the bike on some long rides, and the battery has never let me down.

    Overall, I'm very happy with my purchase. Koa Plus is the perfect combination of style, performance, and practicality. Five stars all the way!
