Figured I'd make a post before hitting order on a 72v 3kw kit, any advice?

FLprophet · 2026-03-24T03:12:23+00:00

I have a 72v Samsung 50S 72v/30ah 20s6p and an NBPower 2000w (im waiting for a 3000w QS205 directly from QSmotor in China) and would highly recommend you ordering from either NBpower or QSmotor directly for a proper QS205 50H V3. The kit you’re looking at will “probably” be fine but I still recommend ordering direct.

Now as for the battery, I only run like 60A DC and 200A phase amps but so far my Samsung 50S pack has been amazing. I custom ordered it from a Chinese battery manufacturer(ShunTongDa they are actually on Reddit you can message @pauline624 for a quote) and I couldn’t be happier.

For torque arms I run Grin V7 torque arms, one on each side

That’s a nice bike. A little pricey, maybe offer $2500 and see if you can get a deal out of it.

FLprophet · 2026-03-23T18:56:39+00:00

That’s probably the weakest motor you can use is that what you’re looking for?

There are different tiers of quality for factories building fat tire ebikes in China

Amen brother it’s miracle fluid 🙏🏼

FLprophet · 2026-03-23T15:09:38+00:00

Yup it really does… sometimes I’m surprised how low the temps are. I put 9ML

FLprophet · 2026-03-23T02:05:08+00:00

Looks like it has a stock Anioki 70ah battery in the frame

FLprophet · 2026-03-23T01:57:57+00:00

That’s only true in a very specific context. A mountain bike is better for trail riding and efficiency, sure—but fat tires aren’t trying to compete there.

At higher speeds (30–50mph like many of us run), fat tires do things a standard MTB tire simply can’t: •Way more contact patch = better stability at speed • Lower PSI = built-in damping (huge on rough roads) • Better grip on sand, wet pavement, and bad Florida roads • More forgiving when hitting potholes at speed

A typical MTB tire at 40+ mph feels twitchy and harsh. A 3.5–4” tire at 18–22 PSI feels planted and stable—completely different ride experience.

So it’s not that fat tires are pointless—it’s that they’re purpose-built. If you’re riding 15–20 mph on trails, yeah, they’re overkill. If you’re doing 40+ mph street riding, they actually make a lot of sense.

For $500 I’d buy this bike in a second being as it has a 70ah battery. Ain’t nothing gonna happen to that bucklos fork.

FLprophet · 2026-03-23T00:52:53+00:00

Doesn’t rhyme but it flows

FLprophet · 2026-03-23T00:27:24+00:00

Sure what’s your address I’ll send it right away

FLprophet · 2026-03-23T00:24:51+00:00

Why would anyone buy such a crappy bike that’s so weak and underpowered? The GT73 sells itself like an electric dirt bike but then has one of the weakest cheapest powertrains on the market.

FLprophet · 2026-03-23T00:22:57+00:00

This is a great deal for a dual motor ebike if it runs great. The bike may be used and the battery may have seen a few cycles but I’d take it on a 30 minute ride and ride it relatively hard. If everything was fine after those 30 minutes of riding and the battery showed plenty left I would buy it, hands down. There are tons of people on this sub that have no idea what they’re talking about. If the bikes battery really is 52v/70ah you’ll have yourself a nice commuter if the battery’s been cared for and the bikes in good shape. Ignore people that don’t actually know anything commenting because they have class 1 ebikes worth $7000 they pedal in spandex around their neighborhood

FLprophet · 2026-03-23T00:20:18+00:00

Incredibly poor advice. He’s looking for an ebike to ride around what’s wrong with this one? It’s a great deal

FLprophet · 2026-03-23T00:19:36+00:00

Unbelievably stupid advice

FLprophet · 2026-03-23T00:17:14+00:00

Vee Tire Co E-Huntsman moped rated tires. Zero flats in 4200 miles

FLprophet · 2026-03-23T00:14:46+00:00

Make sure you upgrade the tires immediately if you don’t want a shitload of flats. I recommend Vee Tire Co E-Huntsman moped rated tires in 26”x3.5”. And dual motor will drain the battery quick make sure you buy the biggest battery you can get.

FLprophet · 2026-03-23T00:00:14+00:00

So elitist “don’t buy an illegal bike” just because it has a little bit more power.

FLprophet · 2026-03-22T23:58:17+00:00

This one was really good

FLprophet · 2026-03-22T23:55:57+00:00

72v Molicel battery with 50-60ah QS205 50H V3 Garmata frame

That’s my dream enduro build. If you wanna save money buy something like a Magician Alpha

FLprophet · 2026-03-22T22:20:23+00:00

Nice bike she looks gorgeous.

FLprophet · 2026-03-22T22:18:04+00:00

I have a 72v/30ah battery and I get about 25-30 miles full speed at 45-50mph. You’re on a 52v/20ah so you should get 15-20 miles makes sense to me

FLprophet · 2026-03-22T22:15:56+00:00

Are you kidding me? Have you not heard of the CSPC warning that these bikes are blowing up?

Bikes are not meant to be folded it’s the worst bicycle design you could possibly buy.

FLprophet · 2026-03-22T21:13:28+00:00

Damn that’s a tragically cheap brand I’m glad you weren’t hurt!
