The R.E375 convinces with highest efficiency

How far can I get with my battery and how efficient is my system? These are questions you hear again and again in connection with the topic of E-MTBs. ElektroRad magazine wanted to provide an answer and therefore took an in-depth look at twelve different bikes for its 08-2021 issue, measured their power consumption and determined the efficiency of the candidates in an extensive comparative test.

For this purpose, the editors formed two test groups: E-MTBs with standard motors and larger battery and Light E-MTBs with lower motor power and smaller battery capacity. The ROTWILD R.E375 PRO moves with its powerful motor and the 375 Wh battery exactly between the two test fields, but due to the maximum motor power of 85 Nm it entered the "normal" E-MTBs.

The ultra-compact Shimano drive weighs under 2,500g and delivers up to 85Nm when needed. About three different maps can also configure the support mode itself.

1st place in efficiency 

Clear differences are revealed to the test crew in the bikes with standard E-MTB motors. ElektroRad highlights the R.E375 PRO as particularly efficient: "In medium mode (...) Shimano's EP8 (85 Nm peak) shines on the ROTWILD Enduro with the lowest consumption. Only 250 Wh consumes the drive on the 28km/540 hm round, is with 8.90 Wh/km clearly the most efficient. This is made possible by the second motor profile preset by ROTWILD at the factory, which allows the Shimano EP8 to provide slightly less support in trail mode, respectively, the drive to turn only up to about 60 Nm. Even on the second test lap, ridden in the top motor stage, the EP8 of the ROTWILD is clearly in first place with only 360 Wh current flow".

The 360 Wh battery weighs 1.9 kg and has 20 modern cells of the 21700 cell type with 5,000 mAh.

Pimps the self-confidence

The concept of a lightweight enduro bike with plenty of support when necessary is fully successful in trail use. The test crew notes: "Thanks to a top machined carbon chassis and a deliberately 'small' battery - practically removable at the touch of a button - the R.E375 PRO shines with a comparatively airy 19.75 kg. Per fast 29" wheels and a flat 63.5 ° steering angle pimps the bike in rugged downhills the "self-confidence". Thus, the magazine ElektroRad comes to the final conclusion: "With its pithy, sporty characteristics, the Shimano EP8 is the congenial partner of the light, generally propulsive R.E375. The Japanese motor convinces with harmonious thrust, both at low and high cadence. At the same time, it proves to be moderate in consumption".
