Pedego Pedal Assist

[BoBaBouhy]

Pedego replaced my 2014 City Commuter,(5,000 miles) with a 2019 model because of a cracked frame. The new model's pedal assist is different in that it cuts out power when you hit certain speeds in each level. The 2014 model had even power and did not cut out. This new PAS is terrible and makes for a terrible riding experience. The dealer told me this is how the bikes always performed. I let him drive my other 2014 Interceptor , at which time he admitted that the 2014 had continuous power. He told me the controller perimeters were different and that the new controller was a better system. Can someone verify that newer Pedegos have a differ controller than the 2014 model. Or did they give me a lemon.

If I recall, and I'm no expert, the older controllers maxed out at a higher speed (25 mph I believe) and the newer ones max out at 20 mph MAX. Also, the pedal sensor had a different, less refined system on older models. I don't recall what year the systems were switched over for the production run. I rode an older, first gen Stretch and it hauled butt on top speed but the torque intervention when starting or coming back on the pedals after coasting felt "crude" compared to a newer Stretch.

Hi @BoBaBouhy

Adjustments were made on the controller software architecture to ensure pedal assist power is continually given as the battery SoC drops. This means that on old software when your battery SoC level was dropping during riding your top speed was reduced, the new software the power is consistent until full battery depletion.

The second adjustment made covered a few problems.

• Bunching of Pedal Assists Speeds - The older software had PAS levels that were too close to each other and continual feedback I received was that customers wished they could go slower on lower PAS speeds. This new software fixes that issue while still maintaining those key speeds in the 14 - 20 mph range.
  • New Software
    • 1 = 8
    • 2 = 11
    • 3 = 14
    • 4 = 17
    • 5 = 20
  • Old software was an odd mix of the below data. The SoC being reduced while riding further changed what these top speeds would be.
    • 1 = 11-13ish
    • 2 = 14
    • 3 = 16
    • 4 = 18
    • 5 = 20+
• Needing to meet and adhere to Federal Regulations.
  • Adjustments needed to be made so that the software did not enable the bike to go above 20mph. This was a requirement for meeting Class 1 + Class 2 functionality.
