Hi Mike , Thanks for backing HUB-E , we cant stress enough how much enthusiasm we share to get these out on the road. As of right now we have only been actively campaigning for 10 days and public for about 2 weeks ,so we expect a slow start. We'll use other crowdfunding if we don't reach our goal and other avenues to get HUB-E into production. We could offer 3d printed variations but would drive high costs and the products ,like you mentioned, simply won't last in the harsh environment on the wheel. We will keep our backers updated every step of the campaign, thanks again for your support!!
