Re: Sur-Ron - New Mid drive Bike

Curious if someone can recommend how to customize the Sur Ron as the best street riding bike it could possibly be? My first thoughts are the Super Moto conversion, the street legal kit with the lights and mirrors etc and the belt drive conversion. What about forks, rear shock? Maybe seat? Thanks fo...

Re: Sur-Ron - New Mid drive Bike

My comment was written in a humorous tone, so I'm sorry if you took it too much seriously, as of course there good and bad examples of companies behaviour in every country. In that case, I think it would have been better if you had written “Sur Ron” in place of “Chinese people”. :wink: Also I'm not...

Re: Sur-Ron - New Mid drive Bike

Marketing gimmicks aside, I read 3000$ for the X160 and 4500$ for the X260, and additional discount for preorders. This fact alone will put Luna monopoly in sever danger. I guess Chinese people don't care too much about loyalty: when the big fish shows up asking for 10k+ units, they will be more th...

Sur Ron is actually in our ecosystem. We’re the largest shareholder of Sur Ron.

Re: Sur-Ron - New Mid drive Bike

Interesting find dirk. Will be curious to see what the final prices / specs are on Segway versions of the Sur Ron. They list the x260 version with a 74 mile range! That'd be double what I'm averaging on my Sur Ron. If that's accurate I'll be buying at least a battery from Segway if not a whole bike...

Re: Sur-Ron - New Mid drive Bike

In a hare scrambles you do laps. A 30 second battery swap 1/2 way would help your overall time a lot. Yeah, good call on a battery swap. I would do stuff like this guy but it's kind of lame with 5 hp going that slow. I think one of the reasons why he placed second is because with such tight trails ...

Re: Sur-Ron - New Mid drive Bike

i think you making a mistake. the sur ron is almost too light for some obstacles, it has barely enough weight to plough throw stuff, it gets defelcted way more easily than a full moto bike. once you make it weigh less, especally in the wheels, it is going to deflect off everything, plough through n...

Re: Sur-Ron - New Mid drive Bike

tubliss - not tube less... its a specific product that lets you run 0 psi (it uses a small 100psi inner tube to give a bead seal) Ah - gotcha - neat-o. But I think I'll stick with an actual tubeless setup - I really don't need to run lower than 12psi, and I could probably run at 6psi if I wanted...

Re: Sur-Ron - New Mid drive Bike

Havent done it yet but ill be using tubliss - atleast on the rear tire. Works great on my stealth, and lets you run whatever pressure you want (even 0psi). It's a bit heavy compared to thin tubes and requires some modification to fit the narrower rims but well worth it imo. You can't run 0 psi tube...

Can you go tubeless with stock tyres or need to change them?
I didn't use the stock tires, but I see no reason why they wouldn't work.

Re: Sur-Ron - New Mid drive Bike

Ok I ordered all the parts for tubeless except maybe for the strap. I'm a bit confused what the strap is for anyways? I ordered a strap but not sure if it will work like one suggested Part that confuses me the most is how am I going to get air in the tire fast enough to make it seal? Without a tube...

Re: Sur-Ron - New Mid drive Bike

Yes.. i agree that that statement is a bit much... Then why perpetuate false information? but The three-door hatchback weighs just 2,500 pounds. A Ford Fusion, which is about the same size, weighs 1,200 pounds more than the Kestrel. This increases fuel efficiency by 25 to 30 percent over traditiona...

Re: Sur-Ron - New Mid drive Bike

Hemp 10x stronger than steel? Sorry, but that's just not true.

Hemp might flex 10 times as much steel before breaking, but that doesn't make it 10x times stronger than steel. Big difference, and one wants a frame nearly as stiff as possible.

Re: Sur-Ron - New Mid drive Bike

A quick search shows hemp is not that great of a fiber for strength. Flax is quite a bit better. Fiberglass is more than 3x stronger. And CF at 4127 MPa is about 4.5x stronger using the most optimistic hemp MPa on your chart, and it's 7.5x using the lower value. The hemp angle seems more like a mar...

Make it like a Sur-ron except with better geo, suspension, brakes, and front wheel.
And to me, most importantly, room for a proper rear tire.
