In my case I have Dewalt battery packs. Since they are contained within a plastic case, that also contains the BMS, you couldn't measure them to get an...
How do you define "cut out"? On my old Currie the motor would cut out under high loads even though the batteries still had substantial charge left. In a few...
I would take a whole different aproach to this. -Have participants remove their battery packs and leave them at the Start Line.. -Human power only lap #1 ...
No, I'm eGo-less. But the local dealer is selling 20 or more a month out of a $1200/month storefront in our town of 45,000. The eGo website claims 8,000...
Better quality bricks*( sla's ).. and better chargers play a role in this i suspect. 39ah batteries will last longer than 12ah batteries at similar discharge...
I have workd on Egos and would NEVER own one as it sits. And they require much more Elec. expertise to repair than does an ebike, Lots more independant...
... That is an interesting way to show how much the power-assist helps. ... All races have strict rules, and many sports have rules of equalization. ...
Got to look at those spec.'s and apply what one knows about SLa's: Max Range is calculated using ideal operating conditions, low speeds, and, 100% depth of...
In way of a clarification: Is the longevity of an SLA affected by both the power (for example watts used in climbing a steep hill) and energy drain (%DOD)? If...
My understanding is a 'qualified yes' to excessive current demand shortening SLA life, but in a different way than excessive DOD%. When large currents are...
The comparative disadvantage with PbA chemistries is the dynamic internal resistance of each cell that increases as more current is discharged while the...
... will ... There is no avoiding the fact that a strong rider will do well on an assist bike or a non assist bike. But most of the strong riders out there...
I'm going to abandon the use of my throttle (up to 1000w, "peak") and just let the pedelec (up to 400w, continuous) do the work for the next battery set and...
The local eGo dealer current sells mostly eGos, but also the Zappy 3-wheel truckette, the Zapino, 40mph "Vespa," assorted e-bikes on consignment. A Porsche...
A hill climbing race for 36 miles up a 10.005 ft volcano on a 150 lb ebike loadrd up with batteries hsa beat 99% of the Trained human powered Cycle racers at a...
Having a rule of NO pedaling past 20 mph could be a option but then again a human can pedal 20 mph for hours, resulting in 30 mph motor powered ebikes with...
Only a race up steep hill or long race on the flats a ebike can win the best human cycle racers.I garentee you Lance couldn't beat me up this hill or any...

You have a nice bike but 3 miles in 4 minutes is 45 mph. I'm afraid you would stick out like a you know what around here. How do you think you would do in...
... I'm sure that is possible, winning without pedaling. It would depend upon how the winner is calculated. If your assist bike beat everybody around the...
Sorry about all the posts, but this is helping me figure out the best, fair solution. "eCAT 1 race would be; 12 amp hours max for any Lithium chemistry" Ok...
I can maintain almost 30 mph peadling or not on 8 ah of battery use from a 10 ah battery pack at 72 volts that weight 14 lbs. on a round trip with hills and...
On a flat track I can't do any worse than I do now. I think a 30 mph can be maintained using less than 750 wh in 1 hour to go 24 miles with pedaling. As you...
What happens though when you lower the pack volts to 48V? do you get similar efficiencies? do you have to make gearing compromises? thanks dick ... with...
