Gulas Pi1S: World’s fastest e-bike
Weighing in at 128 kg, the Pi1S packs an enormous 38 horsepower and 100 Nm of torque
If riding a regular electric bicycle can make you feel like you’ve got Lance Armstrong’s legs, this one’s gonna make you feel damn near like Superman. The Gulas Pi1S is a 38-horsepower e-bike that will let you pedal your way past freeway traffic at up to 115 km/h (71 mph).
The very sharp observer might recognize the design here; it’s very similar to the ErockIT bike we wrote about back in 2008. It seems there’s been some corporate shenanigans in the intervening years, but the bike’s original designer, Stefan Gulas, has struck out again with a new company in his name, and a beast of a flagship bike that might just be the fastest pedelec production bike ever.

Weighing in at 128 kg (282 lb), the Pi1S packs an enormous 38 horsepower and 100 Nm of torque. The tires and suspension are much more motorcycle than bicycle, with a 110/70R17 front and a 130/70R17 rear, telescopic forks and a horizontal rear shock.
There’s two different battery options; a 6.5 kWh pack giving around 125 km (78 mi) of mixed-use range, and a 10 kWh giving 200 km (124 mi). Pricing is an eye-watering €19,665 for the 6.5, or €29,438 for the 10.0 (around US$23K and $34K on current exchange rates).

That’s a ton of money, but on the other hand, there’s really nothing else on the market that’ll let you pedal your way crazily down the freeway, grinning like a maniac as car drivers gawp at the strangeness of it all.
The Gulas Pi1S is an extraordinary e-bike that blurs the line between bicycles and motorcycles, offering unmatched performance in the pedelec category. Here’s a detailed breakdown of its features, advantages, and how it compares to other high-performance e-bikes or scooters.
Key Features of the Gulas Pi1S
Performance
- Power: 38 horsepower (28 kW), which is unprecedented for an e-bike.
- Torque: 100 Nm, delivering incredible acceleration.
- Top Speed: Up to 115 km/h (71 mph), making it capable of freeway speeds.
- Weight: 128 kg (282 lbs), significantly heavier than most e-bikes but comparable to some lightweight motorcycles.
Battery Options
- 6.5 kWh:
- Range: ~125 km (78 miles) in mixed-use conditions.
- Price: €19,665 (~$23,000 USD).
- 10 kWh:
- Range: ~200 km (124 miles).
- Price: €29,438 (~$34,000 USD).
Design
- Motorcycle-grade components:
- Tires: Front 110/70R17 and rear 130/70R17.
- Suspension: Telescopic forks at the front and a horizontal rear shock for stability at high speeds.
- Pedal-assist system: The bike requires pedaling to engage the motor, creating a unique « pedelec » experience.
Advantages of the Gulas Pi1S
- Unmatched Speed and Power:
- With 38 horsepower and a top speed of 115 km/h, it outclasses nearly all other e-bikes on the market.
- Ideal for adrenaline junkies or those who want a motorcycle-like experience with pedal assistance.
- Unique Pedal-Assist Experience:
- Unlike traditional motorcycles or scooters, the Pi1S requires pedaling to engage its motor. This creates a hybrid experience between cycling and motorcycling.
- Long Range Options:
- The larger 10 kWh battery offers up to 200 km (124 miles) of range, making it suitable for long-distance commutes.
- High-End Components:
- Motorcycle-grade tires and suspension ensure stability and safety at high speeds.
- Exclusivity:
- Its price and performance make it a niche product, ensuring you’ll stand out on the road.
Disadvantages
- Price:
- Starting at €19,665 (~$23K USD) and going up to €29,438 (~$34K USD), it’s more expensive than most motorcycles or scooters with comparable performance.
- Weight:
- At 128 kg (282 lbs), it’s significantly heavier than traditional e-bikes, making it less practical for urban cycling or manual pedaling without assistance.
- Legal Restrictions:
- In many countries, its speed and power would classify it as a motorcycle rather than an e-bike. This means you’d likely need a motorcycle license, insurance, and registration to use it legally on public roads.
- Limited Practicality:
- While fun and powerful, its size and weight make it less versatile than lighter e-bikes for urban commuting or off-road adventures.
- Charging Time:
- With such large battery capacities (6.5–10 kWh), charging times could be significant unless using fast-charging infrastructure.
Comparison with Other High-Performance E-Bikes
Model Power Output Top Speed Range Weight Price (€) Gulas Pi1S 38 hp (28 kW) 115 km/h 125–200 km 128 kg €19,665–€29,438 Delfast Top 3.0 3 kW ~80 km/h Up to 320 km ~70 kg ~€7,000 Sur-Ron Light Bee X 6 kW ~75 km/h ~100 km ~50 kg ~€4,500 Super73 RX ~2 kW ~45 km/h ~120 km ~34 kg ~€4,800
Key Takeaways:
- The Gulas Pi1S is far more powerful than other e-bikes like the Delfast Top 3.0 or Sur-Ron Light Bee X but comes at a much higher price point.
- Its speed and range rival lightweight motorcycles rather than traditional e-bikes.
- For those who prioritize speed and exclusivity over practicality or affordability, the Gulas Pi1S is unmatched.
Comparison with Honda Forza Scooters
When compared to scooters like the Honda Forza (125 or 350), the Gulas Pi1S offers a unique blend of cycling mechanics with motorcycle-level performance: Feature Gulas Pi1S Honda Forza 125 Honda Forza 350 Power Output 38 hp ~14.6 hp ~29 hp Top Speed ~115 km/h ~120 km/h ~137 km/h Range Up to 200 km Up to ~400 km Up to ~344 km Weight 128 kg ~161 kg ~184 kg Price (€) €19,665–€29,438 €5,499 €6,599 Energy Source Electric Petrol Petrol
Key Takeaways:
- The Gulas Pi1S offers similar speeds but is far more expensive than both Honda Forza models.
- Scooters like the Honda Forza are more practical for long-distance travel due to their larger fuel tanks and quicker refueling times.
- The Gulas Pi1S provides a unique riding experience with its pedal-assist system but lacks the practicality of scooters for everyday commuting.
Who Should Buy the Gulas Pi1S?
The Gulas Pi1S is ideal for:
- Enthusiasts looking for a high-performance pedelec that combines cycling with motorcycle-level power.
- Riders seeking an exclusive product that stands out on the road.
- Those who value eco-friendly transportation but don’t want to compromise on speed or thrill.
However, if practicality, affordability, or legal simplicity are your priorities, options like the Honda Forza scooters or other high-performance e-bikes (e.g., Delfast Top 3.0) may be better suited to your needs.

Prospective buyers will need to register the Pi1S as a motorcycle, and then decide what the heck safety gear to wear with it. A motorcycle helmet, for sure – and you’ll need some armour and abrasion resistance. But on the other hand, you’ve still gotta pedal the thing, so you’re gonna want something with a bit of airflow. It’s also too heavy to pedal once the battery runs flat, so you’ll want to keep an eye on the battery meter.
I have to confess, I think it looks like hilarious fun, and I’ll be putting a test ride on my to-do list for next time I pop through Berlin.

This thing seems like a total blast to ride. My biggest concern would be a pedal-tap leaning into a corner while pedaling. I do it often on my road-bike, but thats only going about 20-25 MPH.
DaveWeselyOctober 18, 2017 01:30 PM
38 Hp is about 18000 watts. The typical person only outputs 100-200 watts on a bicycle. Why pedal?

Thirty Four Grand for a Freakin’ Bicycle? (but YES, please give one to me. I’ll ride it a lot. Thanks!)
Mark PettitOctober 19, 2017 03:09 AM
So if we put pedals on it, its a bicycle? Its registered as a motorcycle, which means you have to have a motorcycle licence…
YouAreOctober 29, 2017 03:26 PM
@DaveWesely – I agree with you reasoning, bar the numbers (38 hp is 28,3 kW), so an average human’s hard legwork is just about half of a percent of the motor’s punch). But if you ride it relaxed, your input becomes completely negligible. Verdict: the bike stands out, but it’s a way too impractical.

My friend in New York makes e-bikes faster than this, and a sh.t load cheaper. Wtf a V4 Ducati Panigale is around the same price.
PaulYakNovember 11, 2017 11:59 PM
Bloody stupid! So expensive why would I buy this when can buy a superb electric custom bike for say $7,500 that will easily achieve 70MPH and a Honda, Ducati or any other motorcycle of my choice for the change $22,500. Or I can have a very odd looking motorbike that my 125cc from 20yrs ago would be faster than, and only cost approx $3000-4000 today.
Some daft rich people might buy them to be very exclusive, as us that don’t waste money will consider the options. Oh and $10k more for an extra 3.5Kw of batteries, are they mental???

The founder of this company is bankrupt. Many people already have lost money during his last scam. And the original bike is the e-rockit bike still existing.
