Haibike MRS The Range Extender

Description

With the Haibike MRS The Range Extender it is possible for you to mount an additional Bosch battery on your e-bike. With a few simple steps it is thus possible for you to obtain a total capacity of 1000 Wh (1x Bosch Powertube 500Wh + 1x Bosch PowerPack 500 Wh) or 1125 Wh (1x Bosch Powertube 625 Wh + 1x Bosch PowerPack 500 Wh). A Y-cable is used to connect the two batteries in parallel.

We offer the Range Extender in the following variations:

  • Option - without locking cylinder.

You will receive only the Range Extender. The lock for fixing the Bosch PowerPack battery is missing. You would have to buy this lock separately.

  • Option - with lock cylinder

You will receive the Range-Extender including a Bosch battery lock, so you can install the Range-Extender completely. Thereby the delivered lock has a random key number.

  • Option - with two lock cylinders and keyed alike

You get the range extender including the Bosch battery lock and a lock for the Bosch Powertube inner frame battery. If you use / install both locks from the set, you can unlock both batteries with the same key.

Note: The supplied lock cylinder is only suitable for models from model year 2018.

  • Option - with TheRailLock, with two locking cylinders and keyed alike.

This option corresponds to the same option as "with two locking cylinders and keyed alike". However, the identical key is also used here to unlock the supplied Haibike TheRailLock.

Note: The Haibike MRS The Range Extender is only compatible for Haibike models that are equipped with the Modular Rail System.

For Haibike models from 2020 with Bosch Powertube 625Wh battery, a lower battery holder cover is required:
(2020: All Mountain 3.0 and 3.5 | Fullseven, FullNine 7.0 and 8.0 | Fullseven LT Life 7.0
2021: All Mountain 3, 4 and 5 | Fullseven / Fullnine 8, 9 and 10 |Hardseven / Hardnine 9 and 10 | Trekking 9 and 10)

The following Winora models are also compatible with the RangeExtender:

Attention: When delivered with 2 locking cylinders, the locking cylinder installed on the e-bike must be replaced.

Modular Rail System

Review with rating of 5 out of 5 stars

Perfekt

Der Extender sitzt auf meinem fullnine.
Habe mir ein bike angeschaut dass mein Händler nachgerüstet hat.
Leider mit der 2-teiligen Batteriehalterabdeckung (Sockel unten). Akku sitzt dann unnötig hoch auf dem Unterrohr.
Anfrage zur Nachrüstung bei meinem Händler: In 2022 nicht möglich weil angeblich nicht lieferbar. Also selbst montieren.

Absolut sinnvoll: 1-teilige, Batteriehalterabdeckung (Artikel-Nr.: 5378) dazubestellen
Dann sitzt der Akku tief und nur etwa 2 mm über der unteren Traverse. Perfekt.

Montage wirklich easy, 45 min max. incl. Demontage Motor.
Achtung: Vorausgesetzt man besitzt das notwendige Werkzeug.

Volle Punktzahl.

Perfekt

Für ein Haibike Sduro S-Pedelec gekauft.
Mein Fahrrad Dealer war nicht in der Lage dieses innerhalb eines Jahres offiziell zu besorgen .
Also bestellte ich dieses Paket und innerhalb von zwei Tagen war es da.
Geliefert wird das ganze in einem Beutel mit ganz vielen Teilen und einer, na ja, sehr übersichtlichen Beschreibung.
Zwar bin ich technisch einigermaßen begabt, aber das ist nicht mein Ding. Mein Dealer hat mir Angeboten das ganze zu installieren.
Ich habe sogar kurzfristig einen Termin bekommen und innerhalb eines Tages wurde das ganze für 60 € installiert.
Einen gebrauchten Akku von meinem Sohn hatte ich glücklicherweise.
Ich pendel mit dem S-PEDELEC zur Arbeit, täglich 50 km+ Fahrten zum Sport, Einkauf etc. Jährlich min. 10.000 km. Problem bestand bei Umwegen und mal eben noch was aus der Stadt holen.
Das Problem ist damit behoben.

Noch ein Tip meines Dealers.
Er musste einen Stecker abkneifen und da für ein Kabel zusammen löten. Ansonsten hätte das ganze nicht mehr mit dem Motor Einbau gepasst.
