Alan, when you use the front brake very hard, the fork receive alot more torque than what a hub motor can produce.. so when you use hub motor the only diff is the direction of that torque... The tire grip is also a major limit for the f...

I found this quote interesting: This model (228LV) turns out to be particularly miserable to control. It's combination of ultra-low resistance (1.12 mΩ) and inductance (10 uH) means you would need to switch ~100 kHz at rated voltage, in order to have reasonable amounts of current ripple just from t...

Re: Stepping down high voltage - 150V to 5V

Methods,

why not using a regular 100-240VAC to 5Vdc adaptor or cellphone charger?.. many times these can take DC at the input as low as 40V dc and can take also up tp 300Vdc too.
:wink:

cellphone 1A charger are VERY compact and cheap! even less than 1 cubic inch with the plastic casing!
