There are a lot of posts here about broken spokes and a variety of solutions. Use the search box in the upper right corner of any page and search all threads for broken spokes, you should get a big return. Good luck!Just after I bought this bike, the rear wheel spokes started to break. I had the whole wheel rebuilt with new spokes. Now they are starting to break again!!!
I ride this bike as carefully as possible mostly on bike paths, some city streets. I weigh 165 and do haveA couple of questions, @Mark: How & where are you riding this bike and are you putting a lot of weight over the rear wheel on the rack? OK, so that's 3 questions ! . This may help us help you determine what's going on. This bike comes with a city street style narrower, 700C rim which might not be appropriate for a bigger person riding on a rocky trail or slamming the motor wheel off a curb. Just a thought.
The wheel smith at REI rebuilt the wheel ( I think is one of the best bike mechanics in Eugene)Who built the wheel? It is easy to over-tighten a hub motor lace. I'd take it back to the wheelsmith. -S
I had it rebuilt with new spokes from Currie, so I do not think they were heavy duty.But if this happens againJust after I bought this bike, the rear wheel spokes started to break. I had the whole wheel rebuilt with new spokes. Now they are starting to break again!!!
DT Swiss spokes for me definitley make a difference @ 15ga. Also, I believe DTSwiss draws out their spokes one by one as opposed to just cutting them from a wire core. Although i've found it easier to break spokes on 700c rims, things like changing the spokes to a thicker gauge, ensuring they are trued regularly, as well as having the mechanic or wheelsmith inspect to see if you can use a different spoke pattern on the wheel can make a difference. That being said, I am about 230 and average 1 popped spoke a month on a non-electric road bike.There's a trade-off between 'heavy duty' and flexibility when it comes to spoke gauge. Ebikes (and Currie bikes) generally come with 13 gauge spokes, some butted, some not. Going with a thicker spoke does not necessarily guarantee no spoke breakage, particularly if the rider keeps all of their weight on the bike when navigating rough roads or potholes. That's a lot of weight over the rear wheel, especially if there's a hub motor built into that wheel. Having some spoke flexing keeps the road from beating up the rider, bike frame and other components; however, the rider has to be active with the bike. If you choose to lace a motor wheel with butted spokes made of really high quality stainless steel, you get a strong but expensive wheel. Some spoke sets like this can cost up to $150 or more and that doesn't include your labor.
