Love my new bike. Original thought it was too heavy and was very nervous about riding it. But practice makes perfect and now I can ride confidently along the bike trails near my house. It handles the unmade trail really well with its big wheels and the seat is sooo.. comfortable Great job Dirodi

This bike impressed me. The battery lasts for over 90km using various assist levels. It is powerful while going up the hills and performs very well, great bike for the money!! The instructions for adjusting the gears were not very clear. I called DiroDi, and they explained how the adjustment should be made.

I used to have an e-bike from another brand, which has only a short range. I had to charge it many times a week. I bought the Primo and no longer have the range anxiety. The bike was delivered quickly. It rides very well and is super comfortable. It feels well built and premium, well down to the design team.
