Hi, new member here. I'm seriously thinking of purchasing my 1st e-bike, and really like the Bulls E-stream Evo FS3 27.5. It will be an all around bike so I'm thinking this would work fine for me over the 2017 Plus model. The dealers are offering a big discount on price for the 2016 model. I was wondering if the firmware update from Bulls works on this model. Do you get the 4 new power modes? Do you get the walk mode? Also, are you current owners still happy with your Bulls? Thanks for your help.
