Re: Protect your batteries from thieves

Have anyone here, had his battery stolen? I've seen some Ebike steal reported, yet never a battery alone. Your best and most convenient safety is a Xena motorcycle disc lock with integrated alarm. They are so sensitive that one can't touch anything on the bike without triggering the alarm. http://ww...

Re: Greyborg Warp Build Planning

Chose a theme colour to complement the black, and make a design of that coulour and black for the canopy.
For one of my bikes that is black, I chose red. Then, selecting red accessories and components, adding some striping, all that makes a neat finished look.

Re: Will this setup work at 88.8V?

Yep, your controller need some minor mod, and it will run the 5304 with 24s Lipo.
If you also beef up the traces, it will feed much more power too.
The 5304 is very happy at 100v and 50+ A, that is the power where it start to shine. :wink:

Re: Cannondale 700 Jekyll Full Suspension, good Ebike?

Both of my ebikes are on steel frames, without rear suspension. So I assume the frames are robust and have no lateral flex. What is lateral flex? Yes, I know it's the lateral movement. But how bad does it need to be to be noticeable? How do you tell when you have it? If I intended to buy a new bike...

Re: Magic pie 3

This oe has integrated cooling, that alone is enough to make it very interesting. The large diameter of the pie is also a plus for performance. I guess it must be available for external controller. The mod shouldn't be too complicated anyway.

I have not built a heavy hub motor in DH frames that have any chance to flex, for I used only racing frames that have very stiff pivots and linkage. Yet I could experiment the difference of kinetic force that the weight of an X5 vs an H series motor, can apply to the swingarm. A heavier motor is har...

Re: Cannondale 700 Jekyll Full Suspension, good Ebike?

Yep, it was a good bike. The odd, one of a kind, monotube suspension fork proved very tough and low maintenance. I would not build one to ride the mountain, but it will be a very good Ebike for the street and mild offroad. The price is high for a bike of this age, but they didn't sell a lot of those...

Re: e-road-bike advice please

If I would be looking for a 250 W, road style Ebike, I would not build it.
There are so many that are readily available, of various quality and price to suit this need.

For me, building my own Ebikes has to be in the purpose of having better power and handling than any commercially available Ebike.

Re: Pingbattery Shipping

Yep, shipping is not an exact science.
I had items shipped from Hong Kong to Montreal in a week, and others that took more than 3 weeks from US.
The most important is that everything I have ordered yet, always arrived. That is a good score IMO.

Re: want into Lipo, what do i need for 30/40miles range

The range depends of how fast and aggressive you ride, and the hills that you may have to climb. Since you have built some Ebikes already, you probably know your efficiency. I average 40 W/h per Km in the mountain, but can do as good as 20 W/h per Km cruising in town. The price of the batteries will...

Re: 0-30mph/48kph in 2.8-3.8 seconds: HOW?

A 700C wheel will always be a bit slow to accelerate, yet it is possible to attain the relatively modest goal that you seek. You must start by feeding the motor, the power that it wants to pull, as much as it is reasonably possible. This means some investment, because in a large wheel size, the moto...

Re: 24" rim help

Drilling larger nipple holes doesn't affect the strenght of the rim. The spoke angle from lacing a large hub though, makes the nipple pulling unevenly, with most of the tension on one side of the hole. That is why it's good to use rim washers, to spread the tension on a larger surface, especially wi...

Yep, it's lose, but I prefer using brass washers to tight fit the spoke head, than pulling the tension of 11 ga spokes from the rim. I would have used 11-12 butted spokes if they could be found. It's an easier job to do with a motorcycle rim of course, but I wanted to avoid the extra weight. I ride ...
