Speed and power limit with new motor

Hi guys,

I`ve got a Kt lcd3 Display and the 20 amp controller installed on my Sondors Custom bike. After a motor damage, I installed a new 350 w Bafang 36v motor (exactly like the old one). Problem is, that now the bike isn`t as fast as it was before anymore, it has a speed limit of 25 kph, even if the Display settings are correct! Since I have two controllers (both 20 amp) which I already tested, I can`t imagine that the problem is generated by this component too. Does anybody have an idea how I could fix this problem please?

Would be very grateful for your advice! Thanks

      I recently purchased an original fatty from a guy that bought it in 2017 but hardly used it as the bike had only 120 miles on the display.  As a result of my upgrade:
      I have the following parts for sale:
      $150.00   Original Sondors 350 watt motor mint, 120 miles of use, Note 350 is in 750 case as upgrade is done by swapping internals in to the old case without removing it.
      $100.00 Original Sondors 36 volt, 8.8ah battery, 2 keys, mount and charger, mint, will cared for
      $25  Original KT LCD3 display, note switch clamp damaged, one of the display clamps damaged but both can be mounted and are stable
      $50  2 Original Sondors controllers, stock 15amp & upgrade 20amp controller.  15 amp never used, 20 amp mint

      Luna Cycle's "preprogrammed" LCD and upgraded 20 amp controller combo
      Does anyone know if the Luna Cycle LCD and 20 amp controller combo is really a different LCD than an original (kickstarter) LCD?  Can I just buy the controller and reprogram my existing display or do I really need to buy their display too?
