Hi I just bought some mountain bikes for my girlfriend and I just to ride for fun and exercise. Im far from a big biker I just got a next power x from walmart for like 100 bucks and took it to the park the same day the seat was very unconfortable so I just bought new ones today. We will occasionally go riding at dark on streets usually not lighted so I wanted to get some lights so people can see us and we can see the road a little better I am not looking to spend a bunch of money but figured you guys would know a decent light that comes with a mount. Thanks
