Good advice is definitely what you get from Matt. I originally ordered the 1000W with 48V 10Ah battery rack conversion kit, thinking to mix commuting with offroad use. Matt called me and asked me heaps of questions on what I actually need (vs wants). Long story cut short, I ended up with a slightly cheaper and different system (500W super tube kit) for my 60km return trip. I can happily report that it doesn’t take much to overtake riders in lycra now – even though I’m one too. Regarding installation of the conversion kit, it’s easier than I thought. The torque bar was the hardest bit for me due to a fat fork on my mountain bike but I did get it on. I also purchased aCycle Analyst to measure all paramaters. These readings may be interesting for the more technically minded people, they were taken with light pedalling (no pedalling only consumes an extra 50-100W). Keep in mind, my mountain bike was already about 20 kg without the kit. The kit added nearly 10kg to the total weight. Monitoring of 500W Solar Bike kit with 11.6Ah Panasonic tube battery: 1. The controller and battery take up to 700W – especially at slow speed, max crank 2. At cruising speed 34-35kph, flat, no wind, light pedaling, it consumes roughly 300W 3. When the voltage drops to 34V (when I’d consumed over 5Ah), the motor alone won’t go any faster than 36kph (maxed out at 360W) on flat ground. Looks like the controller struggles to get more speed once the voltage has dropped a little bit. When the battery is fresh (let say less than 3Ah consumed, where 36V is still available), I have no worries getting to 40kph (around 500W) 4. I’d consumed around 6Ah (of 11.6Ah available) after travelling 28km with considerable pedalling All up, extremely happy with both product, advice and service. Rusdy, Perth |
