Best Ebike

⚠️ warning! don't buy this bike unless you want attention. its a head turner for sure. i get so many people asking questions and giving compliments. even had a few follow me through town just to ask where i got it. I ride this thing to work daily and I've put on just over 400 miles so far with no issues. comfortable and powerful. battery lasts a good 30-40 miles if you're conservative.
