PearTune with Bosch SMART SYSTEM

[JP-NZ]

Still no problems with the Pear Tune. I had a service recently, asked then NOT to upgrade the software system. Bike running like a dream, awesome getting up to full speed on long straight single track.

Hi Johnny, when you say "full speed" on singletrack what type of speed are we talking about?

The maximum speed would be limited by gearing correct? Like the motor keeps giving assistance theoretically forever.

The speed is governed by how fast you can turn the pedals, the assistance doesn’t stop. I guess the maximum speed I’ve reached on the flat off-road is around 45 kph

I have a Pole Voima with the Bosch CX Race motor and the disc speed sensor.
Installed the Peartune PT-MSO-B2-SMART after hating the original 20mph cutoff and riding the bike for a couple of months.

Installation was plug and play and no calibration needed. Hardest part of the install was tucking in the Peartune inside the motor shrouds.

Happy to report no issues so far with the Peartune mod after riding for over 100 miles.

Interesting.

Is your Voima the LED or the ID model? I also wonder whether the fact of rim mounted magnet for speed sensor would make any difference.

European eMTBs are limited to even less than 20mph so the tune would be an interesting updae for my project.

Quick question - will the odometer on my bike record the correct mileage with the chip installed?
