    Hill Climbing Motors

    Thanks again guys for all the replies - they have been very helpful. If I did go for the motor in the link I posted above, which controller would I need to buy to get it working at 48V, 30-35A? I would like the extra voltage just incase I need it, or am feeling particularly lazy and dont want...

    Nice one dogman. If I'm pushing a brushed as hard as a steel geared brushless which one would go first? The brushes or the steel gears? The thing about my commute is that its hilly all the way. The hill I mentioned is just the longest, not even the steepest. I'm fortunate enough to be able to...

    Sorry if I wasnt clearer guys - I guess I'm a little confused. I think I've got it though. Basically what you're saying is that 5 mins on the 5% hill will not put strain on the batteries even if I am pulling 35A for this time. Assume I am using LifePO batteries at 48V, 15Ah. So in this...

    Thank you all for the replies. Very useful. Are the calculations above based on maximum motor output, i.e. 48*35 = 1680W. Does this mean the batteries will be running at full pelt for the the time it takes to clear the hill? The 5% hill goes on for 1.5 miles then turns into a 7% one for around...

    My e-bike enlightened brethren, I currently ride up a 5% hill at around 8mph with leg power alone. If I were to get any geared, brushless hub motor at 48V, 35A would I be able to tackle that bad boy at 21mph? What's the theoretical top speed I could achieve on the hill at that voltage and...
