COVID-19 Important collection and delivery information
Due to a combination of new working practices and demand our lead times for both collection and delivery have been extended.
Where delivery times are stated as a month this is based on the latest information from the manufacturer. These dates should be treated as a guide and may be subject to change. Due to an increase in global demand for bicycles and the disruption in supply during the COVID-19 pandemic supply chains have become very strained. Lead times are based on factory and shipping schedules both of which can be disrupted by delays in component supply and shipping/port capacity.
Should you place a future order with us for a bicycle we will monitor the bike’s ETA and keep you informed of any changes.

Size Options & Purchase
Please note that we are unable to ship this Trek Powerfly 4 Red/Black outside of the UK.
This Trek Powerfly 4 Red/Black 2022 is available with our legendary Podium Point free accessory scheme.
Trek's Powerfly 4 is their most affordable electric mountain bike. It's built with parts that hold up, like a smooth-shifting Shimano drive train, and a powerful Bosch motor. Plus, it features our user-friendly Removable Integrated Battery (RIB) system that's fully encased in the frame yet doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations that you never thought you'd reach on a mountain bike.
It's right for you if...you're sold on the e-bike revolution and want the capability and versatility of a mountain bike at a price that doesn't resemble the car you're trying to use less. You want bigger, better off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.
The Powerfly 4 features a tough yet refined aluminium frame that fully encases a long-range 500 Wh battery for sleek looks, a Bosch Performance CX (250 W, 85 Nm) motor that assists up to 25 km/h, a Bosch Purion controller, a 1x10 Shimano drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means riders of every size get a great fit 29" wheels on larger frames, 27.5" wheels on smaller frames.
Trek's most affordable electric mountain bike comes with the same powerful Bosch motor and intuitive controller as our most expensive e-bikes, with a smaller battery and parts chosen to give you great value.
Please note: This model offers electric assistance up to speeds of 25kph (15.6mph).

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
The following finance options are available to apply for online immediately. If you are collecting your bicycle in store you can arrange your finance prior to visiting the store by selecting the required finance method as well as Click & Collect.
