DARRVIN G-POWER WITH BAFANG

Darrvin’s Bafang mid-drive motor constantly samples relevant information at a frequency of up to 80k Hz via a torque sensor and two speed sensors which are all highly sensitive. In spite of a generous power output and a maximum torque of more than 80 N.m, the motor operates in virtual silence. The Max Drive System puts the rider in complete control. Not convinced? Book your test-ride on any one of our Darrvin e-bike models and experience the technology for yourself.

DARRVIN Arrowpack 500

Capacity

ManagementSystem.jpg

Our battery is designed to seamlessly fit inside the down tube of the frame with the smallest possible area exposed. As a result, the capacity of the battery is maximised and the frame design not compromised, this means it still looks like a bike instead of a shopping trolley. The Arrowpack is simple to insert and remove despite its super secure interface. As a bonus we made sure that the battery pack is directly compatible with all our current models. Our system is 48V with 10.4Ah current.

Management System

The DARRVIN Arrowpack has a sophisticated battery management system (BMS) that controls all of the functions like charging and powering the motor optimally. The BMS also ensures that the battery does not get damaged when discharging and extends its lifespan through protecting individual cells built into the unit. The Arrowpack has a LED display to indicate its condition, while it simultaneously displays the charge on your bicycle computer while you ride. All this is seamlessly integrated with the other eBike components to provide the ultimate riding experience.

Battery Lifespan

There are a few things you can do to ensure great performance and long lifespan:

  • You can charge the battery at any percentage, but it is very important to fully charge the battery when you first receive your DARRVIN e-bike.

  • Hereafter it’s advisable to do a full charge-cycle, once a every three months.

  • When you not going to be using your e-bike for a few days, its best to store the battery off the bike. It doesn’t need a full charge to be stored off the bike.

  • If the battery goes into storage for more than a couple of weeks it should be charged to around 60% rather than a full charge. This will protect it from damage that might reduce the capacity.

  • In all instances, the battery can be charged on or off the bike.

  • A full charge cycle takes 4-6 hours. Temperature and age are factors that play a role in charge time. Under normal conditions, our power-charger will see you out the door in 4hours only!
