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.

Best technological advance since the cellphone

I freakin’ love my new bike!!! I named her Peggy which is short "Peggy Sass” because I feel like I’m flying with her.! I live in the mountains and I now I am fearless with any & all hills. I can’t say enough good things about my Peggy!

Fun bike to ride...

I ordered the bike, it arrived days later. Very easy to assemble, charge, and go. The bike has plenty of zip and the battery life is impressive so far. I was pleasantly surprised at the amount of light emitted from the front and rear lights. I would recommend this bike to anyone in the market for an entry level e-bike as it is loaded with features and is really fun to ride.

A month in with Rev City Bike

Overall I am very pleased with this bike and it’s performance. It was easy to assemble and arrived quickly. The motor is quiet and powerful enough to easily maneuver San Francisco’s hills. It has 3 assist levels. This is my first EBike but in the future I’ll look for a bike with 4-5 assist levels as even the ‘low’ level assist on this bike is quite powerful and sometimes leaves me wishing there was an even lower setting. Also, I bought the smallest frame, 50cm, which advertises as being suitable for riders 5’2 - 5’5. I am 5’4” and the frame is too big. I have to tiptoe which is uncomfortable and if I were a newer rider, I would have returned it for safety. The seat itself however is comfortable and the frame feels sturdy enough. Throttle and shifters are responsive but I wish the throttle was on the right hand side. Battery life is good however removing the battery from the bike is difficult sometimes and can be frustrating. The battery position also makes the bike rear heavy which can make it a little awkward when walking it, especially navigating staircases. I think having the battery in the middle would be a little better. Overall great bike that’s is very fun with a quality and stylish build but has room for improvements in future versions.
