    Replace 14 gauge spokes with 12 gauge?

    I have a front-wheel geared kit on my bike which has 700C wheels and 3 speed internal Nexus hub on the rear. Battery is 10Ah LiFePO4 in an alloy case mounted on rear rack.

    I am continually breaking spokes (14 gauge) on the rear wheel. The front wheel (with the motor) has 12 gauge and I have no problem with that. I am wondering if it's feasible/advisable/practical to get the rear wheel re-laced with 12 gauge spokes? I am guessing there is just too much weight there with battery and a rather "husky" rider.

    Anyone have any suggestions or experience on this? Would it help? and if I got a shop to do it, any idea of cost? Or any other thoughts on how to mitigate this problem?

    Thanks for any guidance.

    More often than not, the problem when breaking spokes is that the spokes are not tensioned high enough and uniformly. Take it to the LBS and have them do this or learn how to do it yourself.

    12 gauge spokes are 2.6 mm in diameter. They would be a real struggle to fit through the spoke holes in many hubs, and impossible in most.
    Also, there's the issue of availability, and the fact that few shops are equipped to custom cut and thread 12 gauge spokes, while many can do 14 gauge.
    I'd consider Sapim Strong spokes, 13 gauge at the elbow, and 14 gauge shaft. I've used them on an electric hub motor with satisfactory results.
    Gearhubs demystified and other cool stuff.

    Simpler - better possibility might be 13ga SS spokes.

    I would look at a heavy rim and 14 gauge spokes, properly built it should take 400lbs with ease. What size is the wheel?
    IGH's, Dyno Hubs, LED lights and old frames

    A Sunringle Rynolight or Mavic a319 are two rims that are very strong.
