★★★★★Rated 5 out of 5
My wife and I are no strangers to the Ebike world. What drew me to this one was not only the price point which compared is actually very good for what you get, but the features really caught my eye. What was lacking in the swagatrons were the shocks.

This was my second ELECTRIC BIKE. The first one was so-so, so I sold it. The HAPPYRUN is AMAZING. Not only is it comfortable, rugged, but man it is FAST. Now 28 is fast to me when you consider my other bike only went 19MPH. This bike is a real game changer for anyone looking for a reliable mode of TRANSIT. I highly recommend this beauty.

Love this bike. Using it to go to work. It's like riding downhill compared to spending an hour peddalling. Directions were a little vague so patience is important but worth it.
