It actually was in the ama amateur rulebook prior to 2024. Many didn't read it closely though. They were only allowed if supplemental race rules said so which was rare. It was better than an outright ban though. My local district even put no electric bikes on every class line in the rules.
The current AMA amateur rule book states that full size ebikes can't race with gas bikes unless it is in the supplemental rules. Is this in the arenacross rule book? My local series told me ebikes are not allowed in any class with gas bikes. It's a bunch of crap.
They should sell for around $49.95 each. They are a polyurethane material. Similar to what the jap bikes use OEM but more durable and flexible. hotfootmotollc@yahoo.com if you would like to place an order. They should be on the site and ebay within a few weeks.
Let me know if you are going to do that. I can put this on hold. I think the stock slider in a better material would be sufficient. I've never seen a worse front slider material. It's almost like holding ceramic.
I had a chance to take a look at the front chain slider to reproduce. It should be an easy pour. The OEM material is terrible for a chain slider. Way too brittle and hard. Our polyurethane will last much longer than the stock part. It won't crumble or crack either. I have to 3d print a few plugs...
Autobody filler works well to build up old sliders. Some type of epoxy might work as well. Once finished, they will be available on our site and ebay. Let me know.
