What you should know about the Enviolo Hub

At Modmo, our Saigon Ebike has undergone numerous iterations and upgrades but one exciting change that we’ve seen in the last couple weeks is the integration of the Enviolo CT hub. The Saigon has the option to be upgraded and equipped with the CT hub and compatible TR shifter. The main benefit of this is the fact that it will be incredibly easy for the CT hub to be upgraded to the TR hub in the future should you decide to. Let’s jump straight into what you should know about the Enviolo Hub.

Enviolo’s NuVinci Technology

Enviolo is a division of Fallbrook Technologies and is the moving standard for bicycles and Ebikes alike today. Utilizing NuVinci technology, the continuously variable transmission (CVT) technology is a game changer. It is a continuously variable planetary (CVP) and changes the way mechanical power is transmitted to improve the performance as well as flexibility of transmissions. This ensures a greener and cleaner future. The CVP is based on a set of rotating, tilting balls fitted between two rings as shown in figure 1. In layman terms, the technology can seamlessly change through a continuous range of gear ratios allowing ebikes to operate at a constant RPM while it moves at varying speeds.

Some key benefits of the NuVinci technology include the ability to provide a smooth and continuous progression from one speed to another with no abrupt ratio changes or harsh gear engagements. It’s light and small with less complexity as well as high torque density. It also doesn’t compromise fuel efficiency for performance while allowing the engine or motor to operate at it’s speed of peak efficiency.

Features And Benefits

The Enviolo CT Hub is designed for the urban commuter and created with simplicity in mind while providing low maintenance. The CT Hub features belt drive compatibility creating the optimal low maintenance and worry free city bike. With a ratio range of 310%, it is able to effectively cover the requirements of diverse city topography. Locked gears are a thing of the past because with the CT Hub, there is continuous variable transmission and stepless control. This enables more focus on the environment such as inner city traffic and also allows the ability to shift at standstill. You’ll be having an easier time riding in stop and go situations therefore eliminating the issues associated with locked gears. Last but not least, the padded print of the Enviolo CT Hub is modern and matches the contemporary bike design of the Saigon.

Great E-Bike, Disappointing Customer Experience

I purchased this e-bike after extensive research, and in terms of performance, it truly delivers. The bike is fantastic—smooth riding, battery life, and excellent motor power. For daily commuting or leisure rides, this e-bike checks all the boxes.
Unfortunately, my experience with the company has been far less positive. From the moment I asked for a spare battery, the customer service fell short. They did not respond to my emails, leaving me feeling ignored and unsupported. Shame MODMO team.
Overall, I love the e-bike but can't fully recommend the company due to their lack of support.

My bike has arrived and I am pleased with it although there is no key for the battery and it does not appear to be removable which isn't what I expected and is a security concern. I have stuck black insulation tape across the headlight to prevent glare into my eyes whilst riding. Have emailed to register warranty and enquire about accessories but still waiting for a response....

My second Modmo

I've had the Saigon for 18 months, and have not been disappointed. There have been a few niggles. The first was the battery was dropping in the frame which meant it wouldn't charge or would sometimes not power on. This was fixed with some simple packing between the battery and the battery cap to keep it in position. The second is chain tensioning - with no horizontal dropouts it's impssible to deal with chain stretch and get the ideal tension. An external chain tensioner solved this, and with a new chain and a 16T rear sprocket, it has been an excellent commuter, easily covering 45miles round trip. The mudguard fastenings at the fork crown and seat stay bridge are made of cheese, so I binned the mudgaurds pretty quickly.
I've upgraded now to the Saigon+, or at least the 2024 edition. The frame engineering is significantly better - the ugly welds have gone and the finish is much better. It's heavier, but I do like the Gates drivebelt and does overcome tensioning issues, in fact, eliminates chain maintenance altogether. The Enviolo gearing is an interesting concept - especially for a single-speed rider like myself. Still haven't made my mind up on it yet, but will persevere.
The user manuals need some work. They haven't been updated for all the Saigon and Saigon+ features, so don't have 100% coverage and you have to find a few things out for yourself.
However - Modmo produce solid and reliable commuters, and well worth the money, once you apply one of the many discounts that they make available.
