Re: Neematic - 20kW middrive bike

I wish SR can make this kind of bike and put into their product line. I assume they are capable of making something similar or better with their engineering and factory setup it is very easy for them to do. price it similar as their current bike will be a killer

Re: Sur-Ron - New Mid drive Bike

most dc-ac inverter is only up to 48 / 60V, no luck finding 67.2V
might have to step down the dc to 12v first.

Re: Sur-Ron - New Mid drive Bike

You can get this new headset, assuming that is what you are referring to. They have all the right sized parts for a 1 1/8 straight steerer. If your DVO emerald is tapered then you will have to get something different. https://lunacycle.com/cane-creek-forty-sur-ron-headset-bearing/ Yep, thanks the e...

Ride it?
Riding it hard always the best way, But in a scenario that you fully charge your bike and decide not going to ride it for a week or longer, I assume it would be better to discharge the battery to lower V

Re: Sur-Ron - New Mid drive Bike

Does anyone know the best way to discharge the battery when it’s Not on the bike? I believe the charger came with it doesn’t do discharge?

Re: E-S LMX 64 Bike Owners

are you guys most using 11speed cassette? What is the reason you need so many ratios on this kind of high performance bike? 7 - 9 speed setup is rather cheap and light , once you go 11-12 speed it gets much more expensive. 11-12 speed gives you the higher gear like 46T / 52T, but why you need that t...

Re: Sur-Ron - New Mid drive Bike

I am also running M403's on both my Light Bees (with x controllers). After every 20 miles + trail rides, all four valve stems look like they are ready to rip off. I have been letting the air out, straighten them up and do it all over again. Tried running as high as 15 pounds and it didn't help (als...

what kind of derailleur and cassette did you end up getting with? does it matter to have bigger gears like 46/5x , 12 or 10 speed on this kind of bike ?

Re: Qulbix Q140MD - any experience?

looks awesome!
maybe also get the motoseat kit, so you can swap later. I found the motoseat is more comfortable than the most comfortable saddle.
any idea the total weight of the bike?

You can re-cell the packs with better cells, Sanyo GA cells have same performance as stock Panasonic PF but you get 37Ah instead of 32
how difficult to swap the cells ? are they all spot welded ?

is it difficult to add a time clock built-in to the LCD display? I found this will be a very useful feature that is not yet mentioned.

Re: Sur-Ron - New Mid drive Bike

There is no doubt that those guys would be charging a lot more for the bike if they could. I don't agree. I think its at an impulse buy price. A nice toy price. It will fit on a credit card price. Raise it much and it is in a completely different category. Even raising it just from $3499 to $3,890 ...

Is there any problem shipping the whole bike with battery to your US customers?
what the shipping cost itself turns out to be shipping a full bike to US ?
