Did you know that last poll I saw on this forum about what wheel size people prefer, over 50% said 83mm… A lot of people want small wheels, which is why I mention the carvons and lack of support.
Honestly, i’m glad carvon worked out for you.
The reason Hummie got into making hubs is because Jacobs were garbage, shorting and falling apart while the wheel slipped.
And I got into it cause my carvons fell apart. Bending axle, wheels slipping, it was a nightmare. When I approached Jerry, I was told I was the first bending truck issue. He asked me not to talk about it. Why? Cause I wasn’t the first person to have bending truck issues, He lied to my face. And many others have told me Jerry did the same thing to them. Then, I got no response at times, followed by shipping this week for 6 months straight, every week. And in the end, the best he did was offer $100 off of the carvon v3’s. This is the worst customer service I have ever experienced.
Why did he need to lie to me intentionally, and cover up the bending truck issues? Will he do the same if problems arise in his new products? My guess is yes, he won’t admit fetal flaws, and instead of accepting he fucked up, he pushed the cost of his mistake onto his customers. Most of the industry works like this. It’s disgusting to me. If you sell a faulty product that can’t be fixed, return your customers damn money and accept that your design failed, not your customer.
If something happens to your hummie motors, we’re here, we’ll fix it and if we can not, we’ll get you hooked up with new stuff at cost (free labor), not just $100 bucks off, cause you know hes at least doubling his costs.
The mounting itself is suspect to me. 3 small screws attach the motor to the truck. If those fail, your motors falling off like a raptor 2.
The pully is the same way, a few small screws hold the adapter on. For us, it’s a thin plate. That plate doesn’t have close to the same forces as the adapter because of the adapters length. More length means more leverage, so the forces on these little screws will be high. If that breaks good bye wheel and hello ground.
With the hub, worst case is you lose a wheel, which happened to me on old hummies because I rode with 2 screws instead of 6, but even then you can ride it out on the can, which I did at 23 mph.
When looking at designs, I want fail safe, and so far, carvons don’t seem fail safe, and they structurally failed for me in the past and were covered up. It’s shaddy, and I honestly don’t trust carvon because of the way Jerry has lied to me. He knew I wasn’t the first person have bending truck issues, and instead of recalling them (which would of meant the end of his business), he made me pay for his design flaws. That’s not an ethical way of doing business in my books.
Maybe my complaints are more about Carvon and not direct drive. But IMO, they will always have some structural disadvantage, since they need to be pushed so far inwards on th truck. Your also limited in motor length. Which will always mean small magnets. Can’t get a super strong magnetic field without big magnets.
