Bosch eBike Sys­tems

Pedal Magazine - - ESystems -

The well-known line of mo­tors from Ger­many’s Bosch com­prise the most pop­u­lar mid-drive e-bike sys­tem.

Be­cause of its well-es­tab­lished rep­u­ta­tion for ex­cel­lent elec­tric mo­tors, Bosch quickly es­tab­lished it­self as an in­dus­try leader and is found on many e-bike brands in the mar­ket­place. There are four motor mod­els in the

Bosch line-up and all are 250W, but each is de­signed and tuned for dif­fer­ent e-bike users. The Ac­tive Line, a mod­ern, el­e­gant de­sign, is for ur­ban e-bikes; the Ac­tive Line Plus pro­vides a versatile, op­ti­mal drive for ex­plor­ing coun­try roads; the Per­for­mance Line is for trekking, all-mountain rid­ing or com­mut­ing; and the

Per­for­mance Line Plus of­fers a max­i­mum torque of 75Nm, which is ideal for e-MTB en­thu­si­asts. Bosch’s in­ter­nal gear sys­tem uses ny­lon gears that mesh to­gether and power a sin­gle chain­ring that op­er­ates at a rel­a­tively high rpm. As Bosch man­u­fac­tures each part of its e-sys­tem, prob­lems are easy to di­ag­nose while the de­sign al­lows all bat­ter­ies and dis­plays to work with each of its mo­tors. Its ba­sic con­trol units, Pu­rion and In­tu­via, are most preva­lent. A new en­try, Nyon, forms part of an in­tel­li­gent sys­tem that com­bines with a smart­phone app and web por­tal to en­able a net­worked e-bike ex­pe­ri­ence. Bosch’s most pop­u­lar bat­ter­ies are its 400 and 500 Pow­er­packs. Ad­di­tion­ally, it of­fers the 500 Pow­erTube and the Dual 500 of ei­ther model, for 1,000Wh of ca­pac­ity.
