My daughters love it when I go bicycle ride with them. I take them to a dirt trail quite a lot and they seem to enjoy that more than the road. I am now looking for some good mountain bikes for them in the $100-$200 range so that I can take them to the next level. Right now their bikes are retro-brakers with no gear, $40 from Wally World. Even came with the crap hanging from the handle bar tips, if you see what I mean... They are 8 years old (twins, yes), but are already taller and stronger than most kids their age (the only bigger girl on their soft ball team is one year older). My goal would be eventually to try the motorized version, but if they just get into mountain biking that would just be cool anyway. I want them to try as many sports as they can (and don't tell me girls should do gymnastics, they tried). Mongoose sounds affordable but looks like a little bit cheap. The bikes also need to have some brighter colors. They don't need Disney bikes but they're girls... Thanks for the help!
