I DM Rad about the spokes. Here is their reply in case it helps anyone.

QuoteHi! We do have spokes available to order. The spokes for the RADExpand5 are 12-gauge, stainless steel, black - 174mm front spoke length - 128 mm rear spoke length. You can purchase as a rear set or front set of 40 each or a smaller set of 6 front and 6 rear together.

Make sure the plug to the motor is pushed in all the way. You can also put some dielectric grease on there and then wrap electrical tape around the connection to keep water out.

I tried yesterday and today and haven't been able to get thru on chat.

Enlever la roue c'est facile. Ca prend un hex pour deviser le garde boue et un gros cle Anglais pour liberer la roue. Aussi il ya un petit ziptie sur la cable electric du moteur, tu dois la couper et remplacer apres.

ATTN!: Quand tu sors la roue du frame il ya deux washers sur le skewer. Ils vont a l'interieur de tes dropouts donc tu dois faire attention ne pas perdre les washer quand to sors la roue. Je l'ai fait 5 fois cet semaine parce que mon pneu est magane alors je dois reparer des flats quaisment tous les jours. C'est un job facile.

Il ya un bike shop sur Papineau pres du Ontario. J'ai juste ete pour acheter des pieces mais le gars ete sympatik. Essaye les. Cycle Ethan c'est un mecano mobile sur la rive sud il va a Montreal aussi, c'est un gars super nice il a arrange la bicyk de ma fillette.

Hi group,

I have a Rad Expand 5 I bought a few months ago. Two spokes are broken off at the hub and I was wondering how to go about replacing them.

If I could upgrade the spokes to make the wheel stronger that would be even better. I'm a pretty heavy rider and because I keep getting flats I'm hauling around a 12v battery to power my tire inflator in addition to all the other tools.

I got the first flat about a week or two ago. And since then every time I repair the tube I get another flat. I'm worried I might have damaged the rim but it looks ok apart from the two broken spokes.

The flats are all on the side of the tube. It appears the tube is getting pinched between the rim and the tire.

I think the tire needs to be replaced. I can get the tire on the rim by hand without using the tire levers. And if I don't inflate the tire carefully it will pop off the rim again. It's like the opening of the tire has been stretched out and it won't stay centered on the rim.

Since I'm a heavy rider I want to replace the rear tire with a motorcycle or scooter tire. And maybe replace the entire wheel or rebuild it to give it more strength.

But for the time being I have limited funds and need the bike to start a new job. And I'm wondering which tire sealant people would recommend as a temporary solution. At least to keep the tubes inflated. And then replace the broken spokes asap.

Hope this post is not too long just want to give a picture of my situation and long term plans. Thanks for reading.
