Re: Sur-Ron - New Mid drive Bike

Pics from my ride on Sunday. Was a good day.
Let's go ride!! I would love to drive to Nevada and ride your trails. I have a 58t on my bike too. Let's PM a time
and place. I have a Mavic Pro and a GoPro for some video. I have one extra battery. I wish we had 2. That would be
an epic day !!

Re: Sur-Ron - New Mid drive Bike

Mathematically its less than 4%, not huge. Steel is tougher than aluminum, but aluminum can be made to be tough. I suspect that Moto Moto's sprockets will be the toughest aluminum options out there. 7075 will wear faster than steel but is lighter and easier to machine. I think the aluminum sprocket...

Re: Sur-Ron - New Mid drive Bike

Isn't anodizing the best for toughening up aluminum? Sure, but I have this bling obsession to cut the chamfers or in this case corner rounding after anodizing. You can't anodize over anodize. I will rub the bare surfaces with a polish that also leaves a protective film. Done. I will be selling the ...

Re: Sur-Ron - New Mid drive Bike

I finished the 58 tooth sprockets in black and pewter. The 52 tooth sprockets will be finished tomorrow in clear and pewter (dark gray) I want to protect the raw 7075 material that is exposed from rounding the pocket edges. One metal finisher says alodine after the anodize and another one says it wi...

Re: Sur-Ron - New Mid drive Bike

58 tooth sprockets coming along. They need to be plated one more time with alodine to protect the exposed
raw 7075 from corrosion.

Re: Sur-Ron - New Mid drive Bike

Can someone tell me what are the dimensions of the battery pack? I want to order a fireproof box for it. Thanks! Really ? What's wrong with asking about the dimensions of the battery pack? Seems more on topic than folks recommending what micro-brewery to visit. Besides just the battery dimensions, ...

Re: Sur-Ron - New Mid drive Bike

Thank you for the kind words guys. It was overall a nice ride and bike did well and held up fine despite my blowing my one important job as a rider to make sure I didn't pedal strike. Less injury than my last pedal strike on a fixed gear road bike wearing no gear (and last time riding one, though I...

Picture of Sun Tong racing supermoto on the same jump that I did.The second picture is Sun Tong on the second double that I jumped and consequently jacked up the head bearings on the Sur-ron.

Re: Sur-Ron - New Mid drive Bike

I would love to ride with you Luke. But it's not as glamorous as you might think. I ride boring and careful at 60 yrs old. Unless I do something stupid like riding with liquid courage. I did nut up and hit the jumps even though everything was telling me not to. My left ankle hurts, but it's a good k...

Re: Sur-Ron - New Mid drive Bike

I decided to do the 2 double jumps at the supermoto in Boise Id. Sun Tong would not do it and told me I should not do it. I drank a gin and tonic a half hour earlier. The crowd made me do it. This one came up short but I hit the second one pretty well. I landed hard after the second double and it fl...

Re: Sur-Ron - New Mid drive Bike

Make the Agni Sur-Ron happen buddy!!! Or controller swap hot-rodding existing motor should be capable of a good deal more power, as I rarely get the stock motor over-temp until riding deep sand for extended periods. At your way better riding skills level do you run into the stock motor reaching max...

Re: Sur-Ron - New Mid drive Bike

So no $h!t, there I was, driving home from work today about 1640 aka 4:40PM on I80 east of a mustang ranch turn off east of Reno when I passed a truck, maybe a Dodge Ram, pulling a Travel/possible Toy Hauler trailer with 2 SUR-RON bikes in the truck bed. Hey Kim!? was this you? Those were my bikes!...

Re: Sur-Ron - New Mid drive Bike

Yeah, no offense but that guy on the 450 was pretty much a newb. However, motomoto was riding on the beginner's track anyway so that makes sense. Plus, 450s typically make 55+ hp and 32+ ft-lbs of torque...something a Sur Ron couldn't match. However, it does weigh over double the Sur Ron so that ma...

Re: Sur-Ron - New Mid drive Bike

Got the first 58t done. I am doing 30 pcs. 15 black and 15 dark gray. Next will be a 52 tooth and I will do 22 pcs.

After that I don't know.

Re: Sur-Ron - New Mid drive Bike

Now that I think about it my idea there was likely not a good one, the state of the art MTB downhill forks are probably not designed for use with a 100 lb motorcycle, more suited for flying off cliffs while mounted on a 30 lb carbon bike. One second thought if a set of small WP forks like comes on ...

Re: Sur-Ron - New Mid drive Bike

I must have the older fork then. BTW, do you have any 58t sprockets laying around I can buy? I have a factory 58t that I got from "Sun Tong" a guy that works for Sur-ron and and is a dirt national champion in China. I let him borrow a Sur-ron bike when he came over to scout the US national supermot...

Re: Sur-Ron - New Mid drive Bike

So I was not happy with the Fast Ace fork from the beginning. The RST Killa fork that came on the test bike was awesome with zero maintenance. With the Fast Ace, the right side started weeping oil from the seal after the first easy ride. The factory sent me a new one right away. After several weeks ...

Will these be available? Luna said no when I asked them about the factory sprocket. I am the guy that designed and make all of Luna's fancy Bafang sprockets. I will sell these Sur-ron sprockets when they are finished after anodizing on my website at www.sur-ronusa.com Luna might also sell them at s...

Re: Sur-Ron - New Mid drive Bike

Maybe. I need to finish some bafang sprockets and then the Sur-ron sprockets are next. Any reason you want a 53t ?

Here is a factory 58t. It is heavy in steel but good for wear.

Re: Sur-Ron - New Mid drive Bike

these headlight / fairing from denzel eastgem looks like it may be a pretty good fit ..
Looks awesome . I will check it out. I carbon fiber front fender would look great. I've studied doing CF but
it's a lot of careful work and more effort than I want to put in, but I'd buy one.
