ボッシュ Bosch eBike ”電動自転車”ユニット。350Wモーター、時速45km!!! 2012年30社以上が採用へ
eBike イーバイク、もうこれは電動”アシスト自転車”とは言えない。ドイツの電動工具メーカーボッシュが開発したペダル付き電動バイク用のユニットは、2012年、あのバイクメーカーのKTM他、30社以上に採用される見通しとなったようです。

このボッシュの350W ボトムブランケット内蔵モーターユニット、何がすごいといって、”軽く時速45km”出てしまうのです。というのもこのモーター、500Wぐらいのパワーをもっているのです。これまでのユニットが時速25km、これだって結構早い。それが、45km/h越えとなると、それはすでに日本の電動アシスト自転車の範疇を完全に飛び出ています。なんと呼んだらいいかって!?
eBike いーばいくです。航続距離は45-105kmぐらいのレンジの商品が出てきそうですが、このDrive Unit 45の詳細は、
アシストは3モードあり、最大は250%! 日本は、最大は50%ですから、両者の違いは明確です。バッテリーパックも36 V- 8 Ahでなかなか強力です。走りはYouTubeで見つけた参考ビデオをご覧ください。新しい乗り物という感じですね。
ドイツ、ヨーロッパのeBike、無茶苦茶楽しそうなことになってるって感じですね。
プレスリリース / Bosch,August 2011
・"Eurobike 2011" Bosch presents new eBike drive for speeds of up to 45 km/h 350-Watt bottom-bracket motor for powerful support
" ・Enhanced driving experience with powerful 350-Watt bottom-bracket motor
・Drive-off support - cycling without the muscle power
・Bosch now an established supplier on the electric bike market, too
Bosch is debuting its new eBike drive system with the "Drive Unit 45" at the "Eurobike" international trade show in Friedrichshafen from August 31 to September 3, 2011. Compared with the existing standard drive for speeds of up to 25 km/h, the new drive enables speeds of up to 45 km/h, thereby allowing electric bikers to reach their destinations even faster with plenty of power in reserve.

Off to a smooth start with drive-off suppor
The new drive-off support feature is exclusive to the new “Drive Unit 45”. No pedal power is required to start the eBike, just the electric drive itself. No matter what gear is selected, it enables speeds of between six and 18 km/h to be reached without muscle power.Powerful electric motor with energy in reserve
The driving force behind the new drive system is the powerful 350-Watt electric motor, which can generate output as high as 500 Watts for short periods with up to 50 Newton-meters of torque. These values clearly show that there is no shortage of energy reserves for effective thrust, even at high speeds or off-road. All this, and the battery still has a range of between 40 and 105 km depending on mode and terrain.With outstanding Bosch reliability as standard
The eBike drive from Bosch is powerful, robust and maintenance-free. It is capable of withstanding puddles and rain as well as impact from flying stones when riding off-road.
Bosch engineers were exacting in the development of the drive. Drawing on the experience of the world's leading automotive supplier, they subjected it to tough environmental conditions such as salt mist, industrial conditions and extreme temperature changes.High-speed eBikes no longer bicycles in the eyes of the law
Motor-assisted eBikes capable of exceeding 25 km/h are no longer considered bicycles in the eyes of the law in many countries. In Germany, for example, the manufacturer or importer has to obtain model approval (homologation) from TUV. To ride a high-speed eBike in Germany, the minimum requirements are a moped license and a vehicle plate. What's more, eBikes can only be used on cycle paths if these have been approved for mopeds.
