Wifey has done many many kms off road on the back of mine. I have the low seat option and the standard. She prefers the low seat. She lasts about 3 hours between breaks. Off road, I stop every hour or so.
But a full day on fire trails leaves both of us very stiff and sore.
I dropped the bike in the middle of a rocky water crossing on Sunday, and apart from nearly drowning she also smashed her ribs.
She said the seat felt particularly hard for the rest of the ride, and the suspension felt harsh.
