Here is how I plan to lock the bike: Folded, locked with a kryptonite fagetaboutit or New york 3000 and with a Pacsafe to protect the bag and the bike at the same time. Safe enough?

Yeah, they are not as reliable, but that's a trade off between weight and cycle life. As well as bike, I don't want to use disc brake because it adds an inconvenient additional weight even if it's more efficient. For me, I plan to change battery every 2 years as better battery will be on the...

If you don't draw more than 5 amps, why don't you try the NMC cells? 2.2Ah 18650 Li-NiCoMn Cylindrical Battery Cells 1Box 96Pcs - BMSBATTERY It has a much higher gravimetric density (193wh/kg for each cell without BMS and connection). You can then have a safe pack that is either lighter or...

Jerry, how do you do to cycle only with 1.1ah or 2.3ah pack? Do you use very low amps? or do you only use electric assist on hills? I suppose that most of the time you're below 15 mph?

Pacific if Reach - 20" double suspension folding bike Hello there, I'm selling my Pacific If Reach because I'm moving and I can't carry all my bikes with me. The Brompton is more convenient for me as I'll live in a small appartment in London. The bike cost $2000 new: Pacific It's a...

There is a thread on endlessphere about A123 20AH prismatic cells for very very low price from Victoria: Endless-sphere.com • View topic - Group Buy? Dr.Bass Steveo found 7s3p Module! Awesome Price!! A bit of DIY but you may be interested. I'd even be interested if anyone wants to do group...

What's your battery exact chemistry? Is it NMC like BMSBattery? Do you also have some specs such as the weight, wh/kg and number of cycle? And of course, warranty can mean quite a lot of thing, to what % loss of the total capacity is covered by the warranty? Because there is no way a battery...

A123 are basically high power lifepo4. Their advantage over the lighter battery are their lifecycle: This is a screenshot I get from cellman site: 1000 cycle at 100% DOD. Only lifepo4 can do that. But it's heavier. So you have to decide between lighter battery with shorter lifecycle (NMC or...

If you're planning to stay legal, you can go for a Tongxin (max 10-15 mph) or a Cute 85/100 motor. (max 15-20mph) They are geared so more efficient on acceleration (Better than direct drive if you have hills and lot of start and stops) So you would have gain on efficiency (unless you have long...

I think Benjy is looking for a kit for a Brompton. That's why he's trying to get the Crystalyte G209. Why any other hub, he would need to go quite DIY and perform fork extension.

Received my Magicshine MJ-880 today and pluged it to my 12V converter: This light is incredibly small for 2000 lumens and perfect for a small bike such as the Brompton. Just a problem: It makes a lot of heat when I turn it on... still a bit afraid to run it at 12V rather than the 8.4V...

Jerry, if you can overvolt it and see if it works fine to 48V it would be helpful to the tweaking community lol I'd love to have a motor like this doing 20+ mph... ok, this is just my dream... ;)

This poor little tongxin wouldn't live very long with me lol. I need something that can handle at least 700W continuous. :p ps: My heavier conhismotor hub (4.6kg) does 3000W peak and 1000W continuous without breaking a sweat. :)

They told me there were going to have the brompton motor in january and I waited until march... and they still didn't have it. Since then, I'm purchasing a mac motor :)

However, don't forget that disc brakes add a significant weight to your bike. That's why most folding bike don't have disc brake. It's a trade off: Better brake power or lighter bike? Depending on the situation you may prefer the one or the other :)

Thanks rog. Hope that everything is going to work. Will post picture once the light set will be completed :)

Actually it's only a post from a member saying it can handle 18V. But few members use the light at 12V without problem. The only issue is that I've read that it has 10V capacitor... but I suppose the capacitor should be able to handle 12V? Anyway few members managed to make it work at 12V. I'm...

I purchased the slime liquid. It didn't stop me from having puncture. Now I'm testing the slime inner tube, hope it's going to work better.

Yes, I plan to use it with my main battery :) If I use 3 diodes, I'm going to loose 9W. That's huge compared to the power of the light at 24W. Almost half of the power would be lost in heat. I've read in endlessphere that the magicshine light can handle up to 18V. So maybe I can give a try...

According to the specs, it uses a 8.4V6.6AH battery. At max luminosity, the battery can last about 2.3 hours: Magicshine MJ-880 NEW 2000 lumen bike light - Magicshine's most powerful light yet. Order from the official Magicshine UK distributor today! So it uses 6.6AH/2.3hours= 2.8A or around...
