Hey guys,
My name is Al and I'm a new viewer/poster on this forum. I'm impressed (and very intimidated) by how much knowledge you all have of electronics and physics. I slept through most of my science classes in school, so going the route of art major in college leaves me at a huge disadvantage in comparison to the rocket scientists who contribute here. So, now that the ass kissing is complete, I'll proceed with my questions about the daily commuter bike I'm contemplating:
I have an old Giant hard tail mountain bike as my donor (30 lbs.). I have a 25 mile round trip commute which consists of rolling hills. By car, one leg of this route (12.5 miles) takes thirty-minutes. The average time I spend at traffic lights is five-minutes. To achieve the same time on my bike, I would have to maintain an average speed of 30 mph. I weigh 155 lbs. and my lunch weighs around 5 lbs. My budget is +- $1500.
Here is the rig I'm contemplating:
- Crystalyte x5304 (rear wheel)
- Crystalyte NiMh 48v 13Ah
http://www.poweridestore.com/NiMH-Battery-Packs/48V-13AH-NiMH-Battery-Box
- controller? (the battery lists 25Ah as its max draw)
- Standard charger which comes with the NiMh battery
- High-speed slick tires
Calculating the amount of battery juice gives me 624 watt hours... right?
How do I figure out how much juice is being drawn from the motor at max throttle? I know it has to do with the controller and how much it sucks from the battery to feed the motor, but what do I calculate using the above mentioned battery?
ANY help would be appreciated. Also, any suggestions about a better setup?
Thanks in advance.
Al
