Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Modmo Saigon SB 700c Electric Hybrid Bike Black 10.5Ah

Brand:Modmo

Code:C:1M1551

The Modmo Saigon SB Electric Bike builds on the popular Saigon S platform, featuring the same lightweight, urban-ready design with the added benefit of a smooth and low-maintenance belt-drive system. Designed for everyday commuting and city riding, it uses a durable 6061 aluminium frame and keeps weight to approximately 18kg, making it easy to handle in busy urban environments.

Powered by a 250W rear hub motor with 5 levels of pedal assist, the Saigon SB delivers responsive acceleration and consistent support on hills and longer journeys. The fully integrated 36V battery provides up to 75km of range and can be quickly removed for convenient charging, with a full recharge time of around 4 hours.

Upgraded with a belt-drive drivetrain, the Saigon SB offers a quieter, cleaner and virtually maintenance-free alternative to a traditional chain. Paired with a single-speed setup, it’s ideal for hassle-free riding in the city, reducing the need for regular upkeep while maintaining smooth power transfer.

Hydraulic disc brakes ensure strong and reliable stopping performance in all weather conditions, while puncture-resistant 700c tyres are built to handle uneven urban roads with confidence.

An integrated handlebar display provides clear information including speed, battery level and distance, while built-in front and rear lights improve visibility and safety in low-light conditions.

Designed with practicality in mind, the Saigon SB features a modular accessory system, allowing you to easily add baskets, panniers, child seats or cargo options without tools. Whether commuting, running errands or navigating daily city life, it adapts to suit your needs.
