I havent had the chance to actually ride one but the Ripz moto bikes look similar to the higher end 72v version. Disclaimer my buddy Wyatt rides for them and he seems to love it and he absolutely shreds on it, he can beat me on a stock 110 if im on a 450 lol

Just an FYI if you have a more standard build (I had a mix of 20s6p and 20s12p designs) and came out to 110pcs at ~$215 shipped for all of it so a higher quantity really brings down the price. I used them for my surron batteries and a husky tc65 conversion

The LB is very similar to trials bike suspension and handling wise in stock form(after properly servicing them and adding oil, at least on the RST I had), the brakes are the biggest drawback out the box imho. I only recently came up with the brake solution of running the formula brakes from cake...

Yea one of the guys who used to ride at the trails I ride at now is on an Ultra and doing hard enduro(keepupwithajones on youtube) and hes already done the X-9000 controller but for me after riding a stock Ultra demo at TKO Idk why anyone needs more for that type of riding and the throttle...

Woah thats strange they are using a BAC4000, wouldnt think that would be ok as their plugs arent water sealed(I got rid of my BAC 4k for that very reason as it cut out on me when it got wet). That does explain a bit of the efficiency though as I bet the ktm doesnt have FOC which does improve...

But from what I can tell there are no published specs on the output, only battery size. With the liquid cooling and possible voltage increase(would be easy for you to measure as you have one) then we could see part of where their efficiency and power are coming from. I wasnt debating to be...

I think you are assuming the cooling is to improve efficiency, its not entirely the case, its only a small portion. Same concept for gas engines, liquid cooling allows you to run at higher performance levels(ie more amps/power) without overheating the system. You still have you inefficiency(heat...

The reason to reduce amperage is to reduce heat, heat is an efficiency loss so if keeping the same power the high voltage is more efficient like you said. The cooling is to reduce heat which is just a way of removing the heat that came from an inefficiency so lower amps and lower heat means less...

Battery size reduction makes sense from weight but it just seems small for racing to me, id think 1.5kwh minimum would be needed for really fast kids riding outdoor tracks. I havent had any experience with the production bikes(own a mod surron and did qs138 build with tc65) but I have heard of...

The battery looks way different than the one on the website. Also interesting that you say the range is better but it has essentially same capacity as the ktm/husky/gg (0.960kwh vs 1kwh). Do you know the voltage? Maybe thats where the efficiency improvement is coming from

Ive not ridden a Alta but Ive ridden bikes that tried odd engineering to create similar feel. The one in particular Ive owned for a while was the 2010 Husaberg FE450 that had the engine rotated 70 degrees so the mass of the rotating assembly acted in a different direction than the typical up and...

Most people that are looking at ix09s are doing hard enduro and running mouse's as the sidewalls can tear as well. Could probably be OK with a tube but for sure they dont work well with Tubliss. The go to tire thats basically same tread with a little more reinforcement and harder...

I have to drive to really ride anywhere. Nice thing is surron can go on the hitch of the car rather than having to use the truck or pull out the trailer for the beta. Mine is the 300 as well.

Yea Im pretty sure I could get close to price of the Ultra for my Light bee but it actually is already a good bike and my dad and wife are the ones who will use it the most now that Ive got a beta xtrainer. I was building the surron for hard enduro but it looks like those events I was planning...

Im in the same boat. I have a heavily modded surron as well(60v65Ah battery, 16 rear wheel, marzocchi shock, ktm 65 front end, KO controller etc). Wish it was at least announced before I started modding mine.

Looks like you can preorder them now for delivery in a few months and price looks good compared to what it would take to get a light be to same battery and power levels. I know I have at least that much in mine and its still a on the small side where this looks perfect size for me...

I had a hare scramble race this weekend and I was running a surron. I have a 65Ah 60v main pack and also have a 17Ah range extender I ran for the race(so just about 5kwh of battery) and my bike is basically a small mx bike setup so its about 150-160lbs(original is 120lbs) and Im about 130lbs...

The molicel P42A is capable of really high output(45A) so based on 100s4p configuration, its capable of 64.8kw or about 86hp. Its the go to cell for surrons so not surprised if its what they use

Its actually less than $5500 more as the surron just went up in price to $4k deliver vs $9400 for the drill. I completely agree it can be done cheaper with the surron but its nice you dont have to get everything tuned and working out of the box. On my surron I just did the BAC4000 and have a...

I really like the looks and performance of these, just the price is a little hard to make the jump vs surron (or the ktm for a little more but they arent really apples to apples). The suspension is the biggest selling point, good forks and GREAT rear shock, but the battery not being easily...
