This man bought the cheapest electric bike on Amazon – a Tuttio – just to see how far he could push it.
Then, he shoved 10 times the power through it with a $15 Bluetooth dongle and a monster battery.
What could go wrong? Explosions, toasted motors, maybe the seat not closing.
He does it anyway, and even promises giveaways if the cheapest electric bike survives the abuse.

Turning the cheapest electric bike on Amazon into a missile
The starting point was a Tuttio e-bike, retailing for about $1,000 with a stock 48V setup.
Not exactly a rocket ship… until Sur Ronster got involved.
And this wasn’t a one-off.
He actually bought four Tuttios for the experiment, meaning he could push one to the limit and still have backups if it blew.
The first move was slipping in a $15 Bluetooth dongle from Amazon, plugged straight into the controller after pulling off the seat and cover plate.
That alone opened the door to basic tuning.
But he didn’t stop at software.
The real madness came when he ripped out the power leads, wired in his own harness with a QS connector, and chucked in a massive 72V 50Ah battery.
The pack barely fit under the seat, forcing him to trim foam, cut plastic, and wedge in extra padding just to keep it from rattling around.
A couple of straps later, and the $1,000 commuter bike was packing superbike voltage.
On the Bluetooth tuning app, he cranked voltage settings, raised phase current, and spun the RPM ceiling all the way to 20,000.
With guidance from LA Rides, he even brought along water bottles – not to drink, but to pour over the overheating motor mid-run.
Old-school field cooling for a very modern problem.
The first full-throttle pulls lit him up.
‘Butter,’ he called it, as the Tuttio ripped to about 40mph.
Against his buddy’s stock 48V setup, the 72V build ran away every time.
But reality hit quickly.
By the time he added the big battery and tweaks, the cost was creeping into RTR territory – bikes that already come with stronger brakes and suspension.
“Don’t dump $2,000 into this to barely beat stock,” he warned.
True to his word, he didn’t hoard the fleet.
Two Tuttios got handed out in person to random riders, and two more are promised to fans in the comments.
This isn’t Sur Ronster’s first e-bike experiment
This isn’t Sur Ronster’s first brush with automotive chaos.
He once bolted a $2,000 mid-drive motor onto a $20 BMX just to see if the frame would survive. Spoiler: it did, barely.
And when he’s not reviving bargain-bin bikes, he’s going the other way – like the time he dropped serious cash on the Bonell 775 MX – a carbon-framed stealth electric mountain bike hiding 6,000 watts.
It looked like a normal mountain bike, but rode like a full-on dirt bike.
Today’s Tuttio build just adds to the lore – another curiosity-fueled automotive experiment.
A cheap bike with stupid power offers one hard lesson: you can hack speed, but the chassis always tells the truth.
