Wonder Maxi WSP6908H Check Discounted Price | L:39.7" W:20" H:43.8" | 280 lbs | 35 lbs | Friction, Felt-pad | Time, Speed, Distance, Calories, Pulse |
The Wonder Maxi WSP6908H is a pretty standard indoor cycling bike. It’s not a commercial model, but definitely has a durable frame construction, close to the sturdiness of at least a light-commercial model. In terms of features, it can be compared with the Merax Silver bike or the Yosuda L-001A. However, it comes with a slightly better performance monitor.

Frame construction
The Wonder Maxi WSP6908H indoor cycling trainer features a triangular frame combining ovalized and 
rectangular steel tubes in its construction. It’s a sturdy bike, rated for a maximum user weight capacity of 280 lbs (127 kg) which is not bad for a home-use trainer. All the steel tubes in the bike’s construction are coated with a rust-resistant and chip-resistant paint finish. The colors used are light gray for the seat and handlebar posts, and a darker gray for the main frame. The flywheel is chrome-plated, while the cover of the belt is made of durable thermoplastic material, as well as the cover of the brake.
The bike’s frame features a step-up bar. This is the slightly oblique bar that connects the seat tube with the main bar of the frame. Not all spin bikes have this bar, so it is quite a plus as it offers the possibility to perform stretches or various spin workouts that require you to repeatedly step up and step down the bike’s frame.
The fully assembled bike is a bit smaller than other models. It is only 39.7″ (101 cm) long, and 20″ (51 cm) wide, while its highest point is 43.8″ (111 cm). This means that it should fit pretty well even into a small room. It is recommended, though, to allow at least two feet of clearance all around it for safe usage.
The bike is pretty heavy. With all the parts assembled, it weighs approx. 90 lbs (40.8 kg). This is more than twice the weight of the average road bike. All this weight adds stability to the bike. Plus, both its base bars feature adjustable levelers while its front base has a set of wheels that allow you to easily move the bike for storage. The bike’s frame does not fold, though.
Seat and handlebars
The Wonder Maxi WSP6908H is equipped with a large saddle designed for improved comfort. Not 
only that it integrates a thick layer of cushioning, it also has a set of springs at the rear that allow it to flex in order to adapt better to your movement. It also has a center cropping for improved breathability.
The saddle is approx. 10.8″ (27.4 cm) and 8.12″ (20.6 cm) wide so it provides plenty of contact surface. Its upholstery is made of durable, double-stitched vinyl material. It also has a standard collar-type attachment system which means you can easily find a compatible replacement for it if needed.
The bike’s seat is four-way adjustable. Its upright post features several adjustment positions while its horizontal slider adds a few extra inches of front to back adjustment. The upright adjustment span of the seat post is not too long, though. It is only approx. 4″ (10.6 cm), from 33″ (83.8 cm) above floor level, to 37″ (93.9 cm) above floor level. This being said, the bike is recommended only for users up to 6’0″ – 6’1″ ( 183 – 185 cm). Taller users may not benefit from a complete leg extension and a correct range of motion.
The bike’s handlebar is only two-way adjustable (up, down); it does not have a horizontal slider like the seat. It offers an adjustment span of approx. 3.5″ (8.8 cm), between 40.3″ and 43.8″ (102 – 111 cm).
The handlebar features a multi-grip design. It offers the possibility to adopt a standard grip, a climbing grip, and a parallel grip. It also has a small loop bar in the middle which allows a close grip. To this bar, you can attach the performance monitor.
The side grips of the handlebar integrate pulse sensors and the included monitor has a pulse reading function. Also, a plastic device holder is included with the bike, accessory that can be attached to the lower section of the handlebar, and can accommodate a smartphone or a tablet.
Drive and resistance
The Wonder Maxi WSP6908H exercise bike is equipped with a 35 lbs (15.8 kg) flywheel. It features a
perimeter-weighted construction for enhanced inertia specific to spin bikes. It has a chrome-plating finish and black ABS side panels for a more aesthetic effect. It is also bi-directional. In other words, you can pedal in reverse but coasting (or free-wheeling) is not possible on this bike. When pedaling in reverse, the resistance and pedaling sensation are similar to the forward pedaling motion.
The bike features a standard friction resistance system with manual action. This means that you don’t have to connect the bike to a power source. But on the other hand, the performance monitor does not have pre-set programs and cannot automatically adjust the resistance.
The bike’s resistance system consists of a felt-based brake pad connected to the frame above the flywheel, and also connected to the tension knob on top of the main bar of the frame. By turning this knob clockwise, the brake applies more friction to the flywheel which increases the pedaling difficulty.
The bike’s brake doesn’t have any pre-determined tension levels. You can tighten it up to the point you can barely pedal. Similar to most other spin bikes with a friction resistance, this brake pad will wear over time and will require replacement. Also, in case the pedaling motion is jerky when you pedal, the pad may require a bit of lubrication with a silicone-based lubricant.
The bike is equipped with a belt drive system. It uses a durable poly-v belt completely covered by the ABS guard. This belt drive comes with several advantages over a chain drive. To begin with, you don’t have to lubricate it periodically. It also generates less vibration than a chain contributing to the overall smoothness of the ride.
Since it’s a bike designed for spin workouts, the Wonder Maxi WSP6908H is equipped with a durable 3-piece crankset. It features pretty long and solid cran arms and metallic pedals, so, as long as you don’t exceed the specified 280 lbs (127 kg) weight capacity, it should support you with no problem.
The included pedals don’t have SPD elements for spin shoes, but they do have standard (9/16) threads so compatible replacements are widely available. They do have toe cages with adjustable straps if you need to secure your feet on them.
Performance monitor
Although the performance monitor unit included with the Wonder Maxi WSP6908H indoor cycling
bike doesn’t have pre-set programs or online connectivity, it still offers quite a few extra features over the average basic unit. To begin with, it features an LCD display divided into six sub-sections in order to show up to six workout metrics at once. It tracks time, distance, speed, calories burned, and pulse.
The monitor unit offers the possibility to select targets for time, distance, and calories from the Up/Down buttons and Enter for confirmation. Once a goal is selected, the monitor counts down from the selected value until it reaches zero.
The performance monitor unit is battery-powered. It requires a CR2 battery which is included. It starts up when you begin pedaling and also has an automatic turn off function. It should turn off after a few minutes of inactivity on the bike to save battery.
Assembly and Maintenance
The main body of the bike comes pre-assembled. The flywheel, the brake system, the belt, and the crankset are already attached. You only need to attach the two base bars, the seat post, the seat, the handlebar post, the handlebars, the performance monitor, the pedals, and several other small parts. This shouldn’t take more than one hour of your time. All the tools are included and the manual provides pretty clear assembly instructions.
For maintenance, the bike’s brake pad may need lubrication and replacement after it completely wears out. Other than this, you only need to keep the bike clean and periodically check for loose bolts and parts.
