The verdict
The GT73 is a trending, well-equipped budget bike — but it's not the dirt bike its marketing implies. At heart it's a pedal-equipped fat-tire e-bike styled to look like a Sur-Ron, sold under a rotating cast of labels (Riding Times, Bootime, TST, ENGWE, and more). For around $2,300 you get a lot of hardware — dual batteries, full hydraulic brakes, suspension, lights, a display — and it earns a VoltRipper Score of 63/100. The single most important thing to understand before buying: this is a moto-styled e-bike with pedals, not a purpose-built e-moto like a Yozma, Talaria, or Sur-Ron. Know that, and it can be a fine value; miss it, and you'll be surprised.
What it actually is
The GT73 runs a 2,400 W hub motor, tops out around 35 mph, and carries dual 48V batteries (~1,747 Wh total) with fat off-road tires, hydraulic suspension front and rear, dual hydraulic disc brakes, and lighting. It's genuinely well-specced for the price and UL 2849 certified. But the giveaways matter: a hub motor and functional pedals put it in the e-bike family, not the chain-driven dirt-bike family. It's built to look like an e-moto while legally and mechanically behaving more like a fat-tire e-bike.
There's also a GT73 Pro step-up — roughly 3,000 W, ~50 mph, dual 60V batteries — for buyers who want more, at a higher price.
The label situation (read this)
The GT73 is a generic model resold under many brand names — Riding Times, Bootime, TST, ENGWE, Speedway, and others list essentially the same bike, sometimes with wildly different spec claims (we've seen the same chassis advertised from 2,400 W up to "6,000 W"). What that means for you:
- No single accountable brand, warranty standard, or real aftermarket.
- Spec claims vary by seller — treat the headline numbers as marketing, not gospel.
- Buy from a seller with genuine return/support policies, since you can't rely on a brand behind it.
The honest caveats
- It's an e-bike, not a dirt bike. If you want a real mini-moto feel, this isn't it — the pedals and hub motor tell the story.
- Range claims are fantasy. Listings cite 68–155 miles; those are pedal-assist/low-speed figures. On throttle, plan for a fraction of that (see our range guide).
- No brand pedigree or support. Poor parts availability and no real community — you're on your own for repairs.
- Spec ambiguity. Even wheel/tire sizing is listed inconsistently across sellers; verify the exact configuration before you buy.
Why it scores 63
- Value (its strength): dual batteries, hydraulic brakes, suspension, lights, and UL certification for ~$2,300 is a lot of equipment per dollar.
- Pedigree & support (the drag): a nameless, resold generic with poor parts support scores low on the factors that separate a keeper from a gamble.
- Category mismatch: it's judged as the e-moto it's marketed as — and as an e-moto, the pedal-e-bike underpinnings hold it to a 63.
GT73 vs Yozma IN10 — the trending budget duel
Both are hot budget searches, but they're different machines:
- GT73 (~$2,300): bigger, pedal-equipped fat-tire e-bike; more of a comfortable moto-styled cruiser.
- Yozma IN10 (~$1,200): a true pedal-less mini-moto that feels more like a small dirt bike, for far less money.
If you want the actual dirt-bike experience on a budget, the Yozma is closer to it — and cheaper. If you want a big, comfortable, do-it-all fat-tire e-bike with dirt-bike looks, the GT73 makes more sense.
The bottom line
The GT73 is a legitimately well-equipped budget e-bike wearing a dirt bike's clothes. Its 63 Score reflects real hardware value dragged down by no-name support and the fact that it's not the purpose-built e-moto its marketing suggests. Buy it if you want an affordable, comfortable fat-tire e-bike and you go in clear-eyed about what it is; choose the Yozma IN10 for a truer budget mini-moto, or step up to the value tier for a real dirt bike with support behind it.

VoltRipper is spec-verified and data-driven — we do not claim hands-on testing of this bike. Specs and prices are cross-checked against seller listings and independent sources; where sellers' claims conflict (and for the GT73 they frequently do), we flag it rather than pick the flattering number.
