Yuba Mundo

The Yuba is our workhorse.We use it for going to the city , shopping and scooter transport.

First it was converted using mid-mounted 120mm sensored BLDC outrunner from MGM-COMPRO driven by 32bit controller from the same company. Power was transferred by 8M toothed belt to the rear wheel using CAD designed and CNC milled drive.

Mundo stage 1 specs.:

Power: 3kw continuos

Torque : 30Nm

Speed : 60km/h

Battery : 16s A123 20Ah Lifepoo4 (with 45 min. charge time)

Range : 45km (at 35km/h average)

Payload :200kg

Stage two was a natural evolution of realizing that power isn`t everything. Motor is 80100 BLDC outrunner ,rewound , utilizing some of the existing drivetrain. This setup survived 45 degree heat ,traversing Main Yarra trail with 80 kg payload (plus rider).The original setup would of course perform better (the MGM-Compro motor has a temperature sensor, so the controller adjusts the current to keep the motor bellow 60 degrees C).

Mundo stage 2 specs.:

Power : 1.8kw continuos

Torque: 17Nm

Speed: 50 km/h

Battery : 16s A123 20Ah Lifepoo4 (with 45 min. charge time)

Range: 50km (at 35km/h average)

The Mundo has traveled about 2100kms so far.

Giant Sedona

This bike is a step trough city bike and like the Mundo it is belt driven using CNC machined sprockets.

Advantages of using belt drive over hub motor are weight saving(the whole drive including the motor is 3.8kg with potential 2.5kw continuous power output), better efficiency and excellent torque.

Power of this bike has been tuned down, since is very light and range was more important than speed.

“Aldi” bike

This was one of our early bikes , based on no-name bicycle purchased in Aldi. It has since been scrapped because the frame was too weak , even by bicycle standards. It is the only dual suspension bike we`ve done so far and it runs 5M toothed belt instead of far superior 8M belt.
