The Voilamart Electric Bike Conversion Kit presents a compelling proposition for cyclists seeking to electrify their existing bicycles without investing in a complete e-bike. Designed around a 48V system with either 1000W or 1500W brushless hub motor options, this conversion kit aims to balance performance, adaptability, and ease of installation for riders looking to upgrade their conventional bicycles. Available in both front and rear wheel configurations for 26″ wheels, the system’s modular design caters to diverse cycling needs, from urban commuting to recreational trail riding.
Motor Performance and Riding Dynamics
At its core lies a gearless brushless hub motor available in two power outputs. The 1000W variant delivers a claimed idle speed of 45 km/h (28 mph), though real-world testing suggests actual speeds are influenced by factors including rider weight, terrain, and battery configuration. The motor’s torque rating of 45 N.M proves particularly noteworthy when tackling inclines, with multiple users reporting confident ascents on gradients where traditional pedal power would falter. One rider noted the motor’s “surprising hill-climbing capability” on a converted Apollo Slant frame, achieving sustained climbs without overheating concerns even under sustained load.
The 1500W option naturally extends this performance envelope, though users emphasise the importance of adhering to local e-bike regulations. The inclusion of a programmable controller allows restriction to 250W/25 km/h compliance through connection of specific wiring terminals, a feature praised by commuters needing to navigate UK/EU legal requirements while retaining off-road performance potential.
Controller and Power Management
Central to the system’s operation is the sine wave controller employing three operational modes: Hall, half-Hall, and non-Hall sensor configurations. This tri-mode functionality enhances reliability by allowing continued operation even with partial sensor failure, a design choice that multiple installers appreciated for reducing maintenance downtime. The controller’s waterproofing emerged as a common discussion point, with several users recommending supplementary silicone sealing around cable entry points and aftermarket waterproof enclosures for prolonged wet-weather riding.
Integration with existing bicycle components proves generally straightforward, though the PAS (Pedal Assist System) sensor’s compatibility with various crank designs received mixed feedback. Those running modern square-taper bottom brackets reported seamless installation, while riders with proprietary crankset interfaces occasionally required additional spacers. The inclusion of a thumb throttle provides immediate power access independent of pedalling input, though some noted the ergonomic benefits of swapping to a twist-grip alternative for prolonged use.
Installation Considerations
Compatibility with 135mm rear dropout spacing positions this kit as suitable for most modern hybrid and mountain bike frames. Front wheel installations demand particular attention to fork strength, with multiple reviewers advising against use on suspension forks not explicitly rated for hub motor stresses. The supplied torque arms received praise for their robust construction, though experienced mechanics recommended supplementing with secondary retention systems on aluminium frames.
Spoke tension and wheel truing quality emerged as consistent positives, with multiple users highlighting the pre-built wheel’s durability over mixed surfaces. One commuter documented 1,200+ miles of urban use without requiring re-truing, attributing this to the double-walled alloy rim’s structural integrity. The necessity of specialist tools – particularly crank pullers and freewheel removal tools – was frequently mentioned as a potential hurdle for first-time installers.
Battery Integration and Range
While the kit excludes a battery, its compatibility with standard 48V lithium packs simplifies sourcing. Users reported typical ranges between 25-40 miles depending on assist level utilisation, with one detailed account documenting 32 miles of mixed PAS/throttle use on a 13Ah battery. The controller’s XT60 connector compatibility necessitates attention to battery termination types, with several riders advising procurement of appropriate adapter cables if not using Voilamart’s own power packs.
Regenerative braking’s absence attracted minimal criticism given the kit’s price positioning, though a minority of eco-conscious riders expressed interest in future iterations incorporating energy recovery systems.
Component Quality and Durability
The included rim brake levers with motor cutoff switches proved adequate for moderate-speed stopping, though disc brake adherents universally recommended upgrading to hydraulic alternatives for sustained high-speed use. The plastic controller bag received mixed evaluations, with some users praising its minimalist design while others opted for DIY metal enclosures for improved thermal management.
Long-term durability reports remain generally positive, with one user documenting 18 months of daily use without component failure beyond expected wear on brake pads and throttle mechanisms. The aluminium motor housing’s resistance to corrosion in coastal environments received particular commendation from riders in seaside locales.
User Experience Enhancements
The decision between LCD and non-LCD variants generated significant discussion. While the base model provides core functionality through its LED indicators, multiple installers advocated for the LCD upgrade’s benefits in monitoring real-time metrics like speed, battery voltage, and trip distance. One reviewer detailed their retrofit process for adding an aftermarket display, emphasising the controller’s compatibility with standard communication protocols.
The PAS implementation’s eight-sensor design enables responsive power delivery, though some noted a slight lag when initiating pedalling from standstill. Tweaking the controller’s sensitivity settings via undocumented button combinations (as discovered by adventurous users) reportedly mitigates this concern.
Safety and Regulatory Compliance
Legal adherence forms a crucial consideration for UK riders. While the kit ships unlocked, the straightforward restriction process to 250W/25 km/h via terminal bridging ensures compliance with EAPC regulations. Off-road enthusiasts appreciate the ease of restoring full power for private land use, though all users emphasised the critical importance of verifying local legislation before de-restricting.
The inclusion of brake lever motor cutoffs enhances safety margins, particularly when operating in high-traffic environments. Several commuters highlighted these sensors’ reliability compared to cheaper conversion kits, noting consistent power interruption even during rapid braking manoeuvres.
Comparative Advantages
Positioned against competitors, the Voilamart kit distinguishes itself through motor quietness – a frequently highlighted attribute. The gearless hub’s near-silent operation contrasts with the whine characteristic of geared motors, making it particularly appealing for riders prioritising discreet assistance.
Its dual compatibility with freewheel and cassette drivetrains (via optional adapters) further enhances versatility. Multiple users successfully paired the hub with 7-10 speed cassettes, though those attempting 11/12-speed installations reported chainline challenges requiring creative spacer combinations.
Environmental Considerations
The kit’s sustainability credentials resonate with eco-conscious cyclists. By enabling conversion of existing bicycles rather than replacement, it aligns with circular economy principles. One environmental assessment estimated an 82% reduction in carbon footprint compared to purchasing a new mid-range e-bike, factoring in manufacturing and transportation impacts.
Conclusion
Voilamart’s conversion system succeeds in democratising e-bike technology for mechanically inclined cyclists. Its balance of power delivery, installation flexibility, and long-term reliability positions it as a compelling option for riders seeking to electrify their current bicycles without prohibitive complexity. While the requirement for supplementary waterproofing and specialist tools presents minor hurdles, the overall package delivers robust performance across commuting, recreational, and light cargo-hauling scenarios.
