3 years agoSeems like yesterday that this ebike was only $1799.
With all the ebike brands and model choices in this price range, including some mid drives, its sort of putting S604 in a tough to buy and justify proposition.
ReplyCourt
3 years agoYeah, it’s a big topic… House prices, food prices, lots of things have gone up recently. This trend combines with more companies entering the space, more manufacturers selling direct pushing prices down, some companies having big investors vs. others being more family run so-to-speak. I think that Surface is doing very well all things considered, and they still offer a bike that’s unique in a lot of ways. If you value their unique offerings (torque sensor, multiple sizes and frame styles, the cool brand and nice site with good customer support, the slightly nicer derailleur and spindle, the ability to adjust the speed a bit, the larger battery option, USB charging, even the headlight and adjustable angle stem…) all of that adds to the cost, but definitely stands out to me and would add up or not match as well doing it aftermarket.

3 years agoYes indeed. Once upon a time S604 bikes were sold for $1799, back in 2016-2017. It feels like yesterday, doesn’t it?
Supply chain struggles in the cycling industry are widely known and accepted. Many reasons for price to be higher: 25% ebike tariff, container costs are on average 15k which is up from average of 2-3k pre-covid, RMB fluctuating exchange rate adds around 3-6% to cost, all components went up on average 15-20% (if you can get them at all), overall cost of transportation and doing business domestically went up by 5-15%.
Surface is using higher end components as Court pointed out torque sensor, Samsung/LG battery, Alivio group-set, bottom bracket/cranks, well designed geometry etc. Do you want your bike with Chinese lithium ion cells or with Samsung cells, do you want your bike with Walmart grade Tourney TX groupest sprinkled with unknown Chinese name components or you want Alivio and better, do you want torque sensor or cadence, etc. Every little “upgrade” adds to the cost.
Ride safe!

3 years agoI hear you, and I think the offering is quite good for the price. The components are above average, there’s more choice here, and the company has been around for a long time… yes, time does fly :)

2 years agoI’m a bit confused by the battery case spec. Is the basic battery a Reention Dorado?
ReplyCourt
2 years agoYes, I believe it is a Reention Dorado battery pack. Perhaps you could confirm this with Surface 604, but that’s my best guess ;)
