Know if it definitive that the USA bikes won't have walk assist activated? I've got the Yamaha Haibike, it has the button, but it's not enabled. Would love to have this enabled as I could sure use it in some steep rocky areas.Ron,
None of the Bosch bikes have throttles. There are some systems that have walk assist, but that will only give you power up to about 3 mph. Most of the better bikes these days don't have throttles. I think most find that they don't need them after riding for a bit.
I hope that helps.
Thank you AnnRon, if you're open to considering other brands of mid drives, consider e-RAD, they have a throttle along with the pedal assist and shift sensing. You provide the bike or find one ready to go. I think e-RAD's distributor, Lectric Cycles sells complete bikes with the e-RAD mid drive. Talk with @Chris Head, he can go over all of the fine points of their system.
All of the bikes with Bosch motors are beautiful machines but none of them have a regular throttle, a few have the 3mph walking throttle.
