Who is the Gocycle G4i bike suitable for?

The new Gocycle G4i like previous generations, covers all bases. Folding small enough to fit in a boot, under a desk, in the hull storage of a yacht and even under your stairs at home the new Gocycle G4i can tackle the ultra-urban commute as easily as weekend leisure rides around countryside, light off-road cycle paths and docks and marinas. The worlds first truly fully folding integrated electric bike just got a whole lot better!

Gocycle G4, G4i & G4i+ set a new standard for lightweight design, innovation and performance in the portable urban e-bike segment - Richard Thorpe (Gocycle designer)

Simple, clever, fun

Designed by previous McLaren F1 racing car designer Richard Thorpe, the new Gocycle G4i offers clever simplicity in a new, fun package. 

The G4i is their new mid level folding electric bike but offers much of the spec of the G4 and G4i+ including its patented CleanDrive system, its new motor/gearbox assembly, intelligent 3 speed gearing and new carbon frame components. 

As well as the basic features of the G4 model, the G4i features a larger and more informative built in dash, longer range battery, electronic predictive gearing and daytime running light. The G4i dashboard uses LED lights to provide information to the rider.

This includes: current gear selection, speed, light controls and battery charge state. All of this is built into a clean, easy to use cockpit. This clutter free approach consists of just brake levers and a button each side to operate on demand power & manual shifting. 

Daytime Running Light

The Gocycle G4i is the first in the G4 line-up to feature a daytime running light (DRL). 

New European law states that all vehicles from 2014 are required to have DRL's which offer improved safety to road users by increasing visibility and Gocycle have got ahead of the game on their folding eBikes. 

The Gocycle G4i comes with a fully integrated DRL built into the dash, of course Gocycle take it to a whole new level using patented light pipe technology offering a huge increase in visibility.

Gocycle G4i Folding

The new Gocycle G4i shares its folding frame design with the rest of the 4th Generation model range. Taking less than 10 seconds to fold, the wheels remain in place so the bike can be pushed along. 

Nothing needs to be removed from the bike to fold, but the saddle and post can be quickly removed to further decrease its folded size. A removable battery is now standard across the whole 4th Generation range.

This super simple solution to an easily foldable eBike design means there's no visible cables, no oily chain and no external gears to adjust - Just hop on, and enjoy the ride!

This not only minimises hassle but also makes it a readily "wipe clean product". To keep your new Gocycle G4i in top condition, you only need to wipe it over with soapy water - no fiddly nooks or crannies to get in to! 

The new G4i with its patented CleanDrive system offers an "anti chain slap" system - the chain is silent in motion and when the Gocycle is transported on it's side.

Practical & Stylish

Every aspect of the new Gocycle G4i has been designed to an exceptional standard and a strong focus on usability and ride-ability. Being so simple to use opens  it to riders of almost all ages and abilities. 

Key to its simplicity, the G4i you can be simply unfolded, turned on with the press of one button and you can immediately start pedalling. Its really that simple. Using a torque sensor built into the cranks/CleanDrive system, the Gocycle G4i measures rider input constantly while riding, and applies power when you need it. All you have to do is point it in the right direction!

Two Wheel Drive on the Gocycle G4i Electric Bike

Two Wheel Drive

The Gocycle G4i with its proprietary drive system offers incredible traction and power. Your efforts power the rear wheel directly. While pedalling, this clever bike measures your input, and sends an equal amount of power to the front wheel via its powerful but well hidden micro motor hidden for a quick, minimal-effort, zero emission journey.

This clever design isn't just for speed - it also offers a near perfect front and rear power balance ratio to ensure a smooth ride.

Feeling strong? The Gocycle G4i can be ridden in exactly the same way as an ordinary bike when switched off, in its normal powered mode (with the motor mimicking your pedal input to the rear with power to the front), or you switch to on-demand power at the touch of a button. (Activate on App).

Electronic Shifting

Gocycle specifically designed the cockpit on the G4i to be completely clutter free. Removing the need for a manual shifter, the G4i will automatically shift up and down through gears as the riders pedal cadence increases and the terrain changes.

The G4i can even sense when you've come to a stop and instantly down change down to the lowest gear, readying itself for the next take off!

The Gocycle G4i utilises a patented Shimano Nexus 3 speed hub gear on the rear. The rider can also choose their own gear using the electronic button built into the handlebar grip and the lights on the cockpit will relay the current selection back to the rider. 

Gocycle G4i featuring Shimano Nexus 3 Speed Electronic Gearing

The new Gocycle G4i cockpit comes with ergonomically designed grips with a rotary "on demand" power twist grip on the right. One side also allows the user to quickly change up and down gear at the flick of the grip whilst the other side offers power on demand and doubles up as the DRL (Daytime Running Lights) adjustment from low - high beam and flashing modes.

Gocycle G4i Folding Electric Bike Vgonomic design.

Designed To Fit You

The Gocycle design principle is unique and fits any height of rider, be it 5ft2 of 6ft2. Their trademark Vgonomic™ frame design and geometry system provides fully adaptable fitting with a superior level of comfort for a wide range of body types.

Gocycle models use an automotive inspired adjustable "driving position". Cars of course come in one size with an adjustable position - so does Gocycle. Just as with increasing the frame size on a regular bike increases height as well as length, the angled saddle position means that as you raise the saddle, the bike also gets longer! 

Did you know, the wheel-base, centre-to-centre actually has the same length as a regular bicycle? This means it's more natural to ride & doesn't feel like a smaller more compact electric bike while remaining nimble in and out of town.

Agile & User Friendly

The Gocycle models are the only folding eBikes built to fold so small without removing components, but with true rider's agility and handling. Its light enough to throw over your shoulder, and the overall weight is so well balanced that if you pick it up in the middle it doesn't tilt at all!

Built with simplicity and usability in mind, Gocycle folding electric bikes are a joy to own.

GocycleConnect SmartPhone GX App

GocycleConnect = Ultimate Control

This new application for the G4i models also doubles up as a easy troubleshooting tool & security device.

Gocycle G4i Battery Range

More Range Than Ever

The new Gocycle G4i has the battery built within the frame, but can be removed for off-bike charging for where getting power to the bike isn't practical.
