Drivetrain questions, answered

What does going up ten teeth on the rear actually do?
Divide the new tooth count by the old one. 48T to 58T is 1.21 — roughly 21% more torque at the wheel and roughly 21% less top speed. If your bike did 40 mph it will now do about 33, and it will climb noticeably better.
Do I need a longer chain?
Usually, if you go up more than a couple of teeth. Check your tensioner or swingarm adjustment range first; if it is already near the end of its travel, the chain will not fit no matter what you order.
Should I replace the chain at the same time?
Yes. A chain and its sprockets wear into each other's profile. New chain on old sprockets and the chain wears out in a fraction of its life. Buy them as a set — it costs less than doing it twice.
Will shorter gearing hurt my range?
Slightly, if you ride the same speed. But it helps range on hilly ground, because the motor spends less time lugging outside its efficient range. On flat terrain, taller gearing is more efficient.
How do I know a part fits my bike?
Every part carries a fitment code and we check it against a compatibility database before listing it. Filter any collection to your bike, or email a photo of your frame plate to hello@motorhabit.com and we will answer within 24 hours.
What if it does not fit?
Send it back. 14 days to start a return on any part, no restocking fee, uninstalled and in its original packaging with the hardware bag unopened. If our fitment data was wrong, we cover the return shipping too — that one is on us, not you.

About Drivetrain

Gearing is the cheapest big change you can make to an electric dirt bike, and the easiest one to get wrong. A bigger rear sprocket adds hill torque and low-end pull and takes top speed away in the same proportion; a smaller one does the reverse. Nothing here changes how much power the motor makes, only where it puts it. Run the numbers on the gearing calculator before you buy, or read the 48T vs 58T breakdown for the Light Bee.

Sprockets here are cut from 7075-T6 and hard anodized, in 420 pitch to match the stock chain on Surron and Talaria. Chains are pre-stretched and O-ring sealed so they hold adjustment instead of needing a tug every ride. Tensioners use sealed bearings for the same reason.

Every part shows which bikes it is verified for. Chain slack is set at the tightest point in the suspension travel, not on the stand; the chain care guide covers the 30-second wear check.

Change the ratio, change the bike.
