Thanks bro, keep a look out, I may do a give away

[@maukaman]

Nice work! I’ve been considering making the switch up to a tf8 chain at some point. I’ll say though, I’ve been amazed by what these little 25h chains can handle! I ride on extremely steep hills so when I change sprockets I’ll need at least a 90 tooth, I’ll check out the shop you mentioned. 🤙

[@GypsyTales420]

It is crazy how much those 25h chains can take! I rode those chains for the better part of its transformation lol they could do anything. After I added all the pit bike parts it was a lot heavier tho and the tf8 just made more sense.

[@maukaman]

@@GypsyTales420 So you never even got to a point where you were breaking 25 chains with that motor eh? Good to know. It’s looking like the chain type I choose will be decided more by availability/cost of the correct sprockets rather than by chain strength then. I even found a cheap 92 tooth #25 sprocket on Amazon, wrong bolt pattern but I suppose that one could be adapted for a super duper torque gearing if I wanted. I actually have a little one-wheel trailer that I mount up to pull tools and stuff around the farm sometimes so the torque comes in handy. Sounds crazy but it works really well while in motion 😆

[@GypsyTales420]

@@maukaman well I definitely broke a few lol but like I said they do take a beating. The cost of the chain is about the same either way. I’d love to see your farm trailer that sounds awesome!

[@insungkang5694]

How'd you know that the wheel was gonna fit the axle for the razor?

[@GypsyTales420]

it tells you the dimensions online, but it doesn't just "fit" the new wheels are 15mm axle hole, where the old ones were 12mm. So you either have to switch to bigger axle and modify swing arm, or use axle bushings to make up the difference, which is what I did, links are in description.

[@paulcook8356]

I can’t find any sprocket even close to this that will bolt to these wheels. Your link does not advertise T8f on their site when clicking your posted link.

How did you mount the rear brake caliper? What size rotor is on the rear? How much did they charge you for the rear sprocket? That is a really nice build.

The rear caliper mounts to axle, it’s not perfect but it works and locks tire up when you want it to. I’m not sure the size of rotor it all came in a kit, it’s larger than 200mm though for sure. Rear sprocket was $70 plus shipping. Thanks bro, I think I’m gonna do a give away for it. Keep watching.

[@matthewlizardi1148]

Also do you think the electro and co swing arm is long enough to fit the bigger rear wheel or should I be looking for a longer swing arm

[@GypsyTales420]

Electro and co didn’t have any of these parts when I built the bike. The only offered the motor battery and controller. I would go with their stuff it’s probably a better fit. I’m 6,3 so the bigger stuff fit me better but I could tell the extra weight was definitely at the limits of the controller/motor. It all just depends on how crazy and custom you wanna make buddy.

[@PatOutdoors]

Do you notice a big change in rotational mass added? Have you weighed this bike? Been looking at a similar wheel/tire/suspension set up for one of my bikes and just wanted to get an idea of the weight added.

[@GypsyTales420]

Definitely a big change. It’s way more solid. It is definitely a lot for the motor/controller. You can tell by how much the volt meter drops when accelerating, much more energy is used. It’s probably at its limits, you would need a bigger motor/controller if you weighed over 220, I’m about 200 and I can tell it struggles on steep hills, Kelly controller beeps with a controller hot error code. I’d like to try a 17/14 wheel set up it may be a better fit. The forks are incredible though. I haven’t weighed it but it’s close if not a little heavier than the sur ron lol

How did you pick the number of teeth for the rear sprocket? So i have a 6inch streach and running 12 back wheels. I was about to order a custom made sprocket with 72 teeth. is my gearing going to be way off?

[@GypsyTales420]

There's good videos on here about gear ratios, and some online calculators you can try also. I guessed and actually bought two different sizes and went with what worked best. There's a lot of factors like the wheel size, the stretch, your weight, the type of chain you are using, and what your overall goal is. I have a 64 tooth that gives it a lot more top speed (almost 50mph) but the acceleration and hill climbing lacks, the 90 tooth only goes about 37mph but has crazy acceleration and hill climbing ability. Im not an expert, sorry if this wasn't helpful.
