    Surly Big Easy on hills with a passenger?

    I increasingly find myself daydreaming about a Big Easy. But if I bought one one of my very frequent routes would have me doing a fair amount of climbing sometimes with someone on the back deck... anyone have any sense of whether the motor on one of these things can handle it? (I know it would depend on how much pedal input I'd add, so lets' assume there'd be decent effort from a moderately fit rider (which I realize is hardly a scientifically precise measurement but.. )
    Fat, tired.

    With that type of motor the level of assistance can be dialed in accordingly.
    For example using a lower gear for those steep hills + heavy load...
    The Big Easy is designed for heavy loads and pulling a trailer...

    One of my bikes is a peddle assist dual sus with 3" tyres and a Bosh CX motor, the same as the Big Easy. I did a ride up a mostly fire trail and single trail track a 1000 Km's long called the Munda Biddi here in Western Australia with it. I had 45 Kg's in a BOB Ibex trailer on the rear and 15 Kg of crap in panniers and rack on the front. [I carry a lot of camera gear] I use USD forks for that very reason. I never once had to get off due to weight or steepness being an issue. My 11 speed changing was an issue, changing under load into granny [46T] was near on impossible under load. I've ridden the MB on non peddle assist bikes and have had to hike a bike numerous times.

    Walk assist with a load is absolute crap, it just cuts out because it has no torque.

    The levels of peddle assist are very similar to each mechanical ratio having the benefit of being multiplied by 4 electrical ratios. Indeed, if one is in granny + Turbo, brick walls are no obstacle!!!! {OK, maybe a bit over the top, but you get the drift...} I have never had the motor overheat or cut out for any reason, that includes using it in 40 degrees C with that load. Be aware of overloading the chain, i.e. being in a high gear and a high boost level with a big load whilst pulling away as the chances of snapping a chain are high.

    Be aware, the claimed Uber long mileages claimed by Bosch are a load of crap. I'm convinced they did their road tests in Holland with a tail wind and a rider that weighed in at 45 Kg soaking wet!!! With a fully loaded bike in rough terrain, I'm hard pushed to get 20 Km's from a 500 Wh battery with the above mentioned load. On tar, I might get 30 Km's with the same load. I weigh 98 Kg. I carry spare batteries which are horrendously expensive.

    Personally, I love the system. I also have a big fat dummy with a Bafang on it and on that bike, really miss the responsiveness and feel of the Bosch.

    My humble opinion, if you have the coin, go for it, I reckon you'll never regret it.

    It seemed like a good idea!...... at the time......
