-ish. The motor bearings sit inside a sealed space which houses the drive chain connecting the motor to the drive cog. So an contamination would need to make it's way through the drive cog's axle bearings, and then through the motor's bearings.
If you want durability, then you want Rocky Mountain's Dyname 4.
It uses a standard bottom bracket, which can easily be serviced to replaced. The motor's cog sits higher in the frame and is protected by a cover with does a good job of keeping water and dirt out. The cog is driven by the motor...
Has anyone removed the chain retention roller when riding cross country?
Removing it would still have the chainring with about a quarter wrap of chain, which is the same amount that a lot of high pivot bikes successfully use. It would also make it much quieter, which would be nice.
Of course...
You're kind of stuck with method already listed since the cranks need a Cinch interface, and only Race Face makes those.
Remember, if you have the Ride cranks they're actually a 175!
Was the bad get off from a jump?
That is hard-fucking-core. My respect for continuing to push through and advocate for yourself and finally getting back on a bike.
Riding dirt I'm knocked myself out before, plenty of blunt force trauma, and some skin dirt rash, but nothing really dramatic. However, riding a bike path once, a car took me out of the cross walk and threw me into the intersection, dislocating and breaking one of my fingers.
My worst injury...
Take a look at Rocky Mountain. From an engineering and sustainability stand point, their system is much better. It uses a standard bottom bracket that's separate from the motor, and the torque sensor is a reliable externally mounted strain gauge. The motor itself is a simply the motor running a...
That stand looks MUCH better, and I'll probably end up picking up a couple.
These are the roll-in stands I'm currently using and they're pretty useless. They might work okay for a road bike, but they suck for an eMTB.
I have a dodgy back, and generally avoid lifting. When I need to put one of the eMTBs in my work stand I have a small ceiling mounted electric hoist I use.
The bike stand would be mostly used for storage. I've tried "roll-in" bike stands, but they don't hold the bike very securely at all.
