Improving Panasonic mid-drive assistance

[Kittenrainbow]

Hello guys

I bought a used "flyer ebike" with the 36V Panasonic mid-drive system.
The bike is great so far. It is licensed for up to 45 km/h in my country. The problem is that I barely reach 30 km/h, even in the highest assistance mode.
So I don't get limited by the 45 km/h limit but by the maximum assistance of the system.

I wondered if there is a way to "convince" the system to add more assistance power. It would be great to reach 35 or 40 km/h in highest assistance mode.
Does anyone know a way to tweak the system in this way?

I had a 24V Panasonic drive bike years ago. The only way I found to coax a little more speed was to install a smaller rear cog.

It was using an internal 3spd Shimano hub and 20t sprocket/cog, IIRC? I found a 16t and that woke it up a little.

Another thing about these if you want to coax more pedal power on hills - don’t pedal smoothly/evenly. Irregular pedal cadence seems to fool the controller into providing power for a startup push. Weird, I know…

As far as hacking the electronics? Hahaha, good luck with that. Panasonic locks everything down tight and I could never figure it out.

Only mod you can make IMO would be rear gearing.

Hey Ykick

Thank you for your reply.
I think you mean a new, smaller cog on the motor, right? Because on the rear I can simply switch gears - or am I understanding you wrong?

Well, I think I'll live with the bike and someday when the batteries are dead or something like that, I'll just get another system

No, I mean smaller cogs on the rear wheel. You may already have the smallest (fewest teeth) which can be used with your derailleur.

My particular Panasonic used an IGH (internally geared hub) of 20-21T which I changed to 16T and gave me a significant boost in top speed.

These systems are rock-solid nice for what they're designed to do but very hard if not impossible to mod.
