Review

I think the system is pretty well designed and a nice take on the dynamo design. The whole system works great and the best part is that the wheels need not be rebuilt. The team working at SunUp Eco seem to be a really friendly and are great to communicate with. They seemingly appreciate the lifestyle of power hungry Bicycle Tourists and have designed a high quality product that works well when put thro the rigours of touring.

We soon realise it was the best option for a dynamo: the most efficient and one that can be adapted on any hub. We were also happy to work with this small company and were really impressed by their professionalism and devotion. And then, the numbers just speak by themselves, we have been cycling 50,000 km with this dynamo. It is really strong and we could always recharge our power bank under all weather, torrential rain, negative temperature, desert heat.

It has been an absolute pleasure to deal with a company who really stands behind their product and is incredibly focussed on customer satisfaction.  It will be my absolute pleasure to recommend SunUp Eco and MaxiDyn(R12W) whenever I have an opportunity.

身為一個身上帶著十幾個電子設備的阿宅來說,沒什麼比充電方案更重要的事情了。我甚至花大錢去買了四片軟性太陽能板,並聯後做成一個太陽能充電器,但是充電效率實在很悲劇。在網路上發現尚品綠能的腳踏車發電機,竟然可以直接充USB裝置,驚為天人。殺去桃園的辦公室,老闆楊總、老闆娘羅姐很熱情地向我解說產品的厲害之處,還請我吃了個便當。我最後也用很低的優惠價入手。我只能說,如果想出國騎車有電力需求的,直接敗下去吧。充電的效能好到國外的車友看了都嘖嘖稱奇,也通過了各種嚴酷的氣候考驗,現在還正常服役中,真可說是台灣之光。
