i am not an expert on bicycles but i know that i can pedal this bmx bike up hills that people have to walk bikes with multiple gears. the frame is light. the parts are durable. the only cons are the seat and the brake pads.

works as advertised so far, but is a bit slower than expected. phones with similar os and specs run faster.

I've been using the transmitter for a couple of weeks now, and it's been great all around. I get no complaints from anyone when I use it for making calls, and the fm strength seems far superior to other transmitters I've used. I have not used the built in Mp3 features yet, but everything else is great. Would recommend.
