Someone quipped, "If you want a guarantee, buy a toaster."
Seriously? Maybe It's because I'm 7 decades into this adventure of life and I've become cynical, and maybe it's just an age thing. But all things are subject to change. BionX made all sorts of promises, where are they? I mean really....
If I based my decisions on someone's promises, guarantees even, I'd have had a disappointing life. But that's me and my corn flakes. Honestly, it's really hard to not call you fffffffffff.....ffffffffaaan.....nnnnn....bbbbboy.
Not to be snide or mean, but maybe to get you to laugh at yourself, at me, and with me. FFS. Every one of the motors I mentioned has been around for at least a decade, several decades, and some even longer. Do you have a stock portfolio with a large investment in Shimano? Really? I started out riding Campagnola equipped bikes. No self-respecting road rider would even consider Shimano for a water bottle holder. And yet in 1973-1976, they started to bury Campy and a few others. I respect them, their products and their aplomb. But I should wait for them to make a hub and until then no one fills the void?
My $3800 Swiss watch has a lifetime guarantee but it cost me $250 every time I sent it in for service. Over 30 years I paid for a second watch in services.
Look, you want me to give the nod to a company that has brought nothing to my plate or business. I'm firmly in the DIY market and a solid supporter of companies that allow end-users to access parts, manuals, and do their own repairs. I'm only going to buy a Bosch, Shimano, or Yamaha mid-drive to have had the experience. Maybe I'll love it. After all I no longer wrench on cages and am in our 10th model Toyota in 40 years. I've never as much as changed the oil and used to do it all with my VWs. But eBikes are my last wrenching hobby. Shimano does nothing for me and my hobby. Sturmey-Archer was making hubs DECADES before Shimano. Now if S-A made hub motors and gave me a guarantee of parts for ten years....
OK, I'm getting overly silly here. There's really not much more to say. I have hub drives. I like my hub drives. My drives have been available for many years and there is a good parts stream. Sadly very few have used drives like the MAC and the one that I know of that has that direct to customer sales model I so despise. I support Bafang products, I like Bafang products. I'm frustrated that the parts stream for BBSxx series is a pain I the arse but no one else fills the void left by their leaving the DIY market. So we slug it out.
