brakes?

so a coaster brake and a front brake is enough? My concern is the coaster brake.
Depends on what your front brake is.
Disc is awesome, V's acceptable for sure.

Our shorthand for C-brakes are calipers that have one mount where a fender mounts.
V-brakes are 2 independent arms that pivot on posts on the frame called 'Brake bosses' and better brakes.

Depending on what you have in front a Coaster back pedal brake in the rear is usually fine.
You can always add a C brake to the back too and I do that myself on bikes with more power than just a coaster rear can stop in a hurry, and that's what it is all about...

You MUST be able to stop as fast as you can go.
If you can't, well, suffice it to say the ending is never friendly, I have the scars and pain to prove it.

Even a well serviced coaster brake is not really up to motorized use. V-brakes are OK, but you're better off with a disc or drum. Discs are fine, I prefer drums for the look but that's just me. You can always put a disc or drum up front, and keep the rear v-brake, then convert the coaster hub to freewheel. There are a bunch of YouTube vids and online tutorials on how to do that. Lastly, don't know how old your daughter is, but after you get it built, you should ride it first. Then if anything goes wrong on the first couple rides, you'll get hurt and not her.
 
Yup, there is an exact break lever for that. This is one of several web stores that sell them, but might not be the cheapest http://www.bikeberry.com/engine-kit-parts/accessories/sunlite-alloy-dual-brake-lever.html
"For Cantilever or Caliper brakes" - when it comes to brakes and lever's, you need to be mindful of "cable pull" or how much cable the lever can pull. caliper and canter pull cantilevers have a different cable pull than a disc or direct pull cantilever (read V- Brake). Problem Solvers makes an adaptor called a "travel Agent" to fix this compatibility issue.

My 2 cents on brake types: A high quality road caliper (Dual and triple pivot only [not really suitable for MAB's due to tire and reach clearance}) or center pull caliper or V brake properly set up is going to be better than the cheapest disc. Good Disc's are the best hands down though. The only thing close in stopping power are top of the line caliper brakes, but good luck getting those to fit tires wider than a 28C. And don't forget pads. A good set of high quality pads will make you think you upgraded the whole system and this is true for ALL brake styles.

I'd just remove that coaster brake arm and forget it was ever there (DON'T DO THIS). There are a couple of OK caliper brakes with a proper reach for a cruiser, the Tektro 559 long reach comes to mind. There are also adapters that will bolt in where a caliper would go and they have cantilever mounts, which would allow you to use either center pull or "V" brakes. Mavic, among others used to make them. But good luck finding them. You could go disc with a bolt on adapter but that would require a change in rear wheel. Feel free to PM me if you have any questions about compatibility.

Worst brake advice ever.
The brake arm attached to the frame keeps your axle from turning.
Besides, they are a good emergency brake and you never remove a braking option ;-}
 
I did some reading and you guys are absolutely right. It's been a decade sense I last encountered one of those so thanks for setting me straight.
