The Engineering

What You Actually Get

7,500W Direct Drive, and Silent With It

A 72V direct-drive hub rated 4,000W nominal and peaking at 7,500W, making 400 Nm. Direct drive means no gears to whine, so the loudest thing on the bike is the tyres. Ben pulled 30 mph off the line in mode three and lifted the front wheel doing it.

40 to 43 mph Up the Hill

The hill test is normally where power claims fall apart. The GT600 accelerated up it in mode three and held 40 to 43 mph the whole way, which Ben was not expecting from a direct-drive motor.

203mm Rotors at Both Ends

Dual-piston calipers on 203mm rotors front and rear, the same caliper and pad at both ends. From 28 mph it stopped with a bike and a half of room left inside the 20-foot marker.

NFC Ignition

Two NFC cards in the box, one to keep and one to carry. Tap it on the display to wake the bike. The battery also locks into the frame with its own key.

Fully Tunable Rear Coil

Preload for your weight, a blue compression knob for the terrain, and a red rebound knob to stop it feeling like a pogo stick. The inverted fork adds its own compression adjuster on top.

Pedals That Actually Turn

A chain tensioner and a single sprocket, no derailleur. They work, and Ben is blunt that pedalling it is horrible, but they are there when you want them.

The Bike Cave Verdict

Ben's Take

“If you're looking for a Sur-Ron style, an e-moto, very capable bike that has a ton of power. It's got Sur-Ron power, 50 miles an hour, 400 Newton meters of torque, a ton of power, but it's got all the benefits of an e-bike, with perfectly functioning pedals, with a super silent direct drive motor.”
“It's got NFC, it's got security, it's got a battery you can hot swap. It's got so many perks that an e-moto doesn't have. So it's kind of the best of both worlds.”
“You can pick this thing up right now for a hair over $2,000. That's a fraction of the price you'd be paying for any Sur-Ron style bike.”

👍 What I loved

  • 50 mph on the GPS at 195 lb with gear, against a 55 mph claim
  • 40 to 43 mph up the hill in mode three, accelerating the whole way
  • 400 Nm and it lifts the front wheel off the line
  • Stopped from 28 mph with a bike and a half left inside the marker
  • 203mm rotors and the same caliper at both ends
  • Silent. The tyres are louder than the motor
  • NFC ignition with two cards, and a battery that locks to the frame
  • 500 lb capacity, which almost nothing else in this class touches

👎 What to know

  • The grips spin in your hand and have no lock-on collars
  • Pedalling it is genuinely horrible, no gears and a lot of weight
  • A direct-drive hub is not what you want in deep sand
  • Throttle is not the most detailed in mode three
  • 139 lb is a lot of bike to lift

Frequently asked questions

How fast is the Bibuff GT600 really?

Bibuff claims 55 mph. On the GPS, with Ben at around 195 lb in gear on flat road, it made 50 mph. Lighter riders will see more. The three power modes cap at roughly 13 mph, 24 mph and then open.

How far does it go on a charge?

The 72V 30Ah pack is good for about 30 miles of real riding. Ben covered 16 miles of hard testing and was down to 45V from a full 84V, and reckons the rule of a mile per amp-hour holds here.

How are the brakes?

Better than the spec sheet suggests. Dual-piston calipers rather than four, but on 203mm rotors at both ends with long pads. From 28 mph it stopped with roughly a bike and a half of room left inside a 20-foot marker.

Can you pedal it?

Yes, and Ben would rather you did not. There is a single sprocket and a chain tensioner, no gears, and 139 lb to move. The pedals are there so the bike qualifies as a bicycle. Bibuff also sell it with pegs instead.

What is the difference between the 7500W and 8500W option?

Bibuff list two motor options at checkout. Ben tested the 7,500W version, which is the one every number on this page comes from.

Is there a discount code?

Yes. THEBIKECAVE150 takes $150 off at checkout on bibuffsports.com.
