ThAt faring and saddle bags are cool! what a score! Also, That hard tail is gonna be harder on your back than not having a front brake! All that being said, your son is what? 10? Since when do ten year olds care about safety or comfort? Chop that tail, toss the front brake, ride it without a helmet. Just don’t get caught at a red light going up a hill!
It’s about having fun and making some memories with your son. When he is old and thinking back on these days what will be a better memory and story? “We chopped that frame up and tossed the front brake and painted it purple, what a crazy fun bike that was!” Or “we spent a week looking for the correct gauge cluster. Oh and don’t get me started on how hard it was to track down those turn signals!” Every time I see a bike with no front brake there is always someone who feels they should point out to everyone how dangerous it is not having a front brake is. Like no one has ever thought about that concept before. What kinda wheels are you thinking? No front brake calls for at least a cool front wheel. I had a midnight maxim that I ran with no front brake just because I loved the stock gold wheels so much.
