Our verdict
Surface 604 suits Canadian and American riders who want a throttle with fat-tire and folding choices under a single roof, starting at $1,499. A 960 Wh battery ceiling and a 5 year frame warranty back it up, though cargo buyers and shoppers outside Canada and the US should look elsewhere.

Pros and cons
Pros
- A throttle is fitted across the range, so riders can pull help on a climb without winding the pedals hard
- Batteries reach 960 Wh, against a site median of 436.7 Wh, with claimed range of 150 km
- Finance is available, which spreads the $1,499 entry price into instalments instead of a single outlay
- Frame cover runs 5 years against 2 years on the battery, and returns sit at 7 days
- The catalogue spans commuter, emtb and fat tire, so a commuter, a mountain bike, a fat-tire bike and a folder all come from a single maker
Cons
- The CA and US footprint is limited, so riders in other countries face freight and parts sourcing on their own.
- The $3,499 ceiling pushes into the same money as Kalkhoff's city, hybrid and step through city and step-through range, so trail buyers pay for frame tech they may never use
- Service runs through a partner network rather than company workshops, so repair quality depends on the local shop
- Cargo buyers get a narrower field: Surface 604's commuter, emtb and fat tire leaves out cargo, while Tern lists cargo, commuter and folding
Who it suits
- Canadian and American riders who want a throttle plus a fat-tire or folding bike from a single maker
- Commuters planning around a claimed 150 km on a single charge
- Buyers who want finance at the till and 5 years of frame cover
Who should look elsewhere
- Riders outside Canada and the US, since the CA and US footprint leaves freight and parts sourcing to the buyer
- Cargo and longtail buyers, because Tern lists cargo, commuter and folding, formats outside Surface 604's commuter, emtb and fat tire
- Street riders after a step-through or city bike, since Kalkhoff lists city, hybrid and step through for that use
Pricing
Surface 604 sells complete bikes rather than subscriptions, so there is no introductory rate that steps up at renewal. The catalogue starts at $1,499 for an entry bike and runs to $3,499 at the top end, and that figure is the whole purchase price rather than the first instalment of something recurring. Buyers weighing entry cost against later cost should read $1,499 as a single payment and budget servicing separately, since nothing in this range renews and no fee replaces the sticker price further down the line. The spread between the two figures also tells you what sits at each end: an everyday commuter at the bottom, higher specification machines at the top.
Where it sits among rivals
On entry price, Surface 604 ranks 103 of 149 brands compared, and on the highest price it places 95 of 145. Neither figure puts the brand at either extreme, which is the useful summary for a shortlist: the entry bike is cheaper than much of the set while the top of the range still sits below the priciest machines here. Readers sorting by sticker price will find it in the middle group, and the entry ranking is the number that matters most because it is the figure most comparisons start from.
What it does well
A throttle is fitted, and that is the detail separating this brand from the pedal-only bikes priced alongside it. Batteries reach 960 Wh at the top of the range, and claimed range reads 150 km, which covers most daily riding on a single charge. Cover runs 5 years on the frame and 2 years on the battery. Buyers who pick the wrong bike have 7 days to return it, and finance is available, so the purchase can be spread rather than paid in a lump.
Who runs it
Surface 604 has been trading since 2013 and is based in Canada, selling into Canada and the US. That is a home market and an export neighbour, which keeps support straightforward for North American buyers and thin for anyone elsewhere. The company can be reached on email, phone and help centre, meaning email, phone and a help centre rather than a single route. For questions before and after a purchase, that mix of written and spoken support covers setup, charging and fault-finding without a workshop visit.

Frequently asked questions
How much does a Surface 604 e-bike cost?+
Prices run from $1,499 at the entry point to $3,499 at the top of the range. The spread covers an entry commuter, a fat-tire machine and a folding bike, so the model choice moves the price more than the maker does. Finance is available, which turns the entry figure into instalments.
Is there a subscription or renewal fee to plan for?+
These are purchase prices on complete bikes, not a subscription, so there is no introductory rate that steps up at renewal. $1,499 is the full amount at the point of sale. Spending after that falls on servicing and parts rather than on a recurring charge from the brand.
How far does a full charge go?+
Claimed range reads 150 km, and the largest battery in the range is 960 Wh. That figure comes from the brand rather than an independent test, so riders carrying loads, climbing hills or riding in cold weather should expect less. The biggest pack sits at the top of the range.
Does it have a throttle?+
A throttle is fitted. The drive is a hub motor from bafang, rated 500 to 750 W, so power arrives at the wheel rather than through the frame. Throttle plus hub motor suits riders who want help on a climb without winding the pedals hard.
Where can I buy and ride it?+
Surface 604 sells in CA and US, both North American markets, so shipping, parts and returns are straightforward inside them. Riders elsewhere face the practical questions of freight, local road rules and where a repair happens, since support arrangements are built around those countries.
What warranty and returns come with a bike?+
The frame is covered for 5 years and the battery for 2 years, so the frame carries the longer of the two. Buyers who change their mind have 7 days to send a bike back. The battery line is the one to watch.
What kinds of bikes does Surface 604 make?+
The range covers commuter, emtb and fat tire, meaning a commuter, an e-mtb, a fat-tire bike and a folder. The named models are Sunny Day, Colt, Boar Hunter, Twist. That spread is wider than most single-model brands here, and it lets a household buy a commuter and a folder from the same maker.
How do I get a bike serviced or reach the company?+
Servicing runs through a partner network, so work is done by partner shops rather than a company workshop. Support runs on email, phone and help centre, covering email, phone and a help centre. A partner network widens where help is available, but the result of a repair depends on the shop.
Can I spread the cost of the bike?+
Finance is available, so the purchase can be paid in instalments rather than all at once. It applies across the catalogue, from the $1,499 entry bike to the $3,499 top of the range, and it matters most on the larger models where a single payment is a bigger hurdle.
