Bimoped, I'll take your advice on the tires, that issue seems to come up a lot around here. The kit is the following: EZ Cruizer: Leading Seller of Gas and Electric Bikes in Southern California
It doesn't say what gearbox so I emailed them asking. They responded, "We have the bulletproof 5:1 ratio gear box that you want. TRUST ME you do not want to purchase the 4:1 ratio motor it will last you one ride and the bearing inside the clutch will disintegrate."
Can you tell from the image which one it is? And yes, giving advice to noobs is tough (know this well from my work), so thanks for bearing with me while I learn this stuff
