Haibike Trekking 4 2021 Frame Style Optiions

Who is this bike suitable for?

The 2021 Haibike Trekking 4 eBike is the base spec model in the Haibike trekking range for 2021 built with the new Yamaha PW-TE system and larger capacity 500Wh InTube battery mounted in the frame. Designed for road and light path use. Featuring the 'balloon style' tyres for comfort. It's equipped with essentials like lights, mudguards, pannier rack & a side stand. Popular with leisure & commuters alike, this fast bike rolls well on roads and the hybrid tyre also takes well to light paths. 

 I've had my new sDuro for just a few days now but I have to say that I couldn't be more impressed. It has exceeded my expectations, and they were high. The bike is of very high quality & handles like a dream. 

I must also thank e-bikeshop for the good communications, ease of ordering and delivery service which is first class.

New Features

Featuring the new Yamaha PW-TE system, brand new LCD control buttons and the internal battery design within the frame... The new 2021 Haibike Trekking 4 is a great contender for those just starting out in the world of electric biking.

First off Haibike have opted for the Tektro hydraulic disc brakes. These are powerful and relatively maintenance free.

The Tektro brakes are simple to use and easy to pull, they offer reach adjust so riders with bigger or smaller hands can adjust where the lever sits.

The Trekking 4 comes with a Suntour coil spring fork, giving extra comfort where required across bumpier terrain.

These forks have a quick release wheel mounting; meaning taking wheels on and off is a breeze, should you wish to put the bike in the car for example. This is the same for the rear wheel too.

Shimano Altus 9 Speed on Trekking 4 2021

The gear system on the Trekking 4 is provided by Shimano for 2021. The Altus 9-Speed rear mech provides plenty of gearing to the rider for a mix of ascending and descending.

The gears are controlled by a simple handlebar trigger that selects the gear up and down while pedalling to the riders preference. 

The 2021 Haibike Trekking 4 uses 27.5" (650B) wheels, so optimise the benefits of both 26" & 29" and combine them into one fast rolling, easy to manoeuvre wheel size.

Matched up with Continental Urban tyres, giving a comfortable feel as the broader tyre absorbs the 'British Roads' better & allows for more grip whilst maintaining a fast rolling resistance on the road.

The Haibike Trekking 4 eBike is equipped with all the essentials including front/rear lights (Powered off the Yamaha eBike system itself), mudguards, a rear rack & side stand. Considering all of this and the German build quality, it's a well priced bike of this spec!

It's the only one in the range to feature a built in 500Wh battery and the brand new Yamaha PW-TE drive system. Want more range, torque and a wider range of gears? Consider the model above, it's called the Trekking 7 2021 and has the Yamaha 630Wh battery.

Yamaha PW-TE eBike System on Haibike Trekking 4 2021

Yamaha PW-TE eBike System

The 2021 Haibike Trekking 4 features the brand new 2021 Yamaha PW-TE drive system. This Yamaha motor has a built in quad sensor which applies assistance in a even more efficient and smooth way. It makes the PW-TE the perfect all rounder for different riding styles. 

The assistance is offered in 4 levels - 'Eco+', 'Eco', 'Standard' & 'High'. Now also featuring the Automatic Support Mode which selects the right amount of riding assistance based on the terrain.

This allows the user to fine tune the amount of assistance required during the ride offering complete flexibility and control. The Trekking 4 2021 eBike uses the 500Wh in-tube battery so it's completely concealed within the frame, but can be charged in the frame or removed easily for charging too.

The new LCD display mounted on the handlebars, shows not just how much capacity the battery holds but also the predicted range in assisted miles. Offered with a lightweight and compact charger.

You can learn more / read reviews of the Yamaha eBike system on our blog pages.
