I have just joined this forum, I have had an Orbea Gain D30 since May 2019 and find it a great bike for me at my current age. As soon as I found one I fitted a Tuning Dongle which has been great, I wanted to increase my range but thought the Range Extender from Orbea was way over priced so fitted a 4.4 amphour Balance Bike Battery which fitted nicely in my Frame Bag. This mod has been excellent and works like a dream. I live in Geelong Victoria, Australia and mainly ride the local area but have ridden in a number of other states on tours I have organised. I do have some questions which I will post shortly.
