Re: A letter to Currie Tech

yeah its a good price on a cheap bike but not what most are looking forward to
riding. Careful -that description on amazon.com is for the aluminum design - your getting heavy steel , sneaky and confusing marketing ploy.
i'm looking foward to aluminum chromoly carbon kevlar hybrid designs.

Re: A letter to Currie Tech

My new letter to currie dear currie sales people and tech people, i am waiting for a bike design where the motor drives a continuous variable gear or runs a geared hub like a shimano 8 geared hub but the drive gearing would need to be accessed from both sides -unless the bionic charger design is use...

a really good bicycle frame with high quality fancy components should not cost more than 400 - 500 dollars. beyond that price range your into rapidly diminishing performance returns and your paying for cachet and novelty and rare metals but funcionality will not sbstantially increase on a 2000 dolla...

e-bike categories

i think it might be useful to create seperate categories for hub bikes and motor mounted bikes for e-bike design and testing and photo creations because its hard to sort through the different types of bikes when they're all lumped together. i look through the topics and it would make it easier to fi...

battery voltage/current configurations

are you sure? wouldn't the voltage be the same? would there be any advantage to switching add-on batteries from serries to parallel?

does a higher voltage allow you to back off on the throttle and get the same performance with less current? and longer run time?

Battery voltage switching

does anyone currently use variable voltage switching?

i would like to use a switch to change my battery configuration while traveling to take advantage of higher voltage for increased speed and power for hills; then switch down to a lower voltage for distance.

thanks! i get speed differentials of roughly 1 - 2 mph and power consumption of up to 100 watts more for 20% grade at 50lbs more weight and 5mph -not too much difference; but it increases to 300 watts difference at 15mph- so if you really want to rip up a hill that extra 50lbs makes over 300 watts d...

how weight affects speed and distance

does anyone know how weight affects speed and distance for any given motor voltage set up for instance if the total weight varies by 50lb how would that affect the speed and distance over various grades? a flat grade might just affect acceleration but not top speed but with grades of 5, 10, 20% how ...
